Frequently Asked Questions

What are the differences between the three GlasWeld injectors; The ProVac Zoom, the ecoVac, and the g3?

Let’s break those down briefly; the ProVac Zoom is the only injector that we sell with Z-mount technology. Our latest technological advancement from GlasWeld, allowing you to quickly mount it against the glass, without any threading necessary. Rather than doing 10-15 turns threading it into a stand, contacting the glass, and then doing another turn to seal it. With Z-mount, all you do is push the injector into the top of the stand, and it will click into place. Then continue to push down the injector until it contacts the glass.

The ProVac Zoom was designed with a much thicker seal, allowing you to apply a great deal of downward pressure. Z-mount also eliminates the torque effect you get with any threaded injector, removing radial stress, and the possibility of over tightening the injector against the glass. Radial pressure is the leading factor for a crack to spread during the repair, so by eliminating it from the repair process, you can better ensure an excellent repair. In addition to that, it has less moving parts, does not have a set screw, does not require a cam lock, has a 30% stronger vacuum than the ecoVac (a much quicker vacuum too), and achieves its full vacuum in less than three turns. The zoom is our latest and greatest technology and due to all of those features, a revolutionary product for windshield repair.

Now, the ecoVac is a very good injector. It also uses the ProVac technology and pulls a substantial vacuum (the second strongest in the industry outside of the zoom and g3). It does have a set screw though, it does require the use of a cam lock, and it’s got a couple of additional moving parts that the zoom does not have; but beyond that, it’s a fantastic injector in particular for those who are on a slightly tighter budget. In fact, the ecoVac won the Viewers Choice Award from Auto Glass Digest not too long ago, so it’s an excellent product. Indeed, the ecoVac is less expensive than the zoom and a much less costly than the g3.

Now, what about the g3? The g3 has an additional piston that isolates the resin. The purpose of that is to do a quick moisture evaporation process during your initial vacuum cycle, therefore, removing any moisture before you go to inject the resin. That’s one key thing to understand about the g3. It could be an excellent option for you if you are in a wet climate, where it’s raining all the time, and you know you’re running into wet brakes on almost every job. It’s a great product, it works well, and has a slightly stronger vacuum than the ecoVac.

However, it’s also crucial to understand that the moisture evaporation process can work with any of our injectors. Just follow the steps in our moisture evaporation training video to achieve a proper moisture evaporation and then go right into your repair. Its also only a one minute, so it’s not a huge factor, even if you’re in a wet climate.

Now, as far as the question of which injector would we recommend? We would recommend the ProVac Zoom. It has our latest, most advanced technology, and for the reasons we already mentioned, it helps you to reduce the probability of breaking the glass during the repair. It has faster loading times, provides better looking repairs, decreases your chance of flowering, and is simpler and easier to use. The ProVac Zoom has many benefits and a lot fewer things to keep track of. That’s our recommendation, and why the Zoom is at the top of our list as far as recommendations go.

The truth is in any business first off you need desire and determination and the willingness to work hard and do quality work. That’s true of any company, and of course, it’s always good to have a business plan and an understanding of your local markets. Identifying potential clients; car washes, fleet accounts, dealerships, body shops, detail shops, retail work, etc. is essential. Also determining what your competition is charging and how many competitors you have in your local market to find your niche.

The other thing to factor in is using excellent equipment and supplies. Which will significantly affect the credibility you have when you go to do the job and also the quality of work that you’re able to do. Also, the company that you choose to work with do they provide ongoing support. When you’re on the job, can you call in and get some tips on the repair that you’re working on as well as any issues that you may have along the way with your windshield chip repair equipment, etc.

The other thing to factor in, in getting set up, will you be set up in a shop setting or a mobile setting. Certainly, a mobile environment you have far less overhead working out of a vehicle or even in some places we have windshield repair technicians that work off of a motorcycle, so determining that as well. Indeed, with windshield chip repair you can work in a mobile setting, you don’t necessarily need a shop.

The other factor that you would need to factor in when starting a windshield repair business is signing up for the third-party administrators that the insurance companies use. That’s the third-party go-between their retail customers, their customers, and the insurance company itself. So signing up for them, we have a video on that as well on our frequently asked questions that can help you out in understanding that process.

The great thing about windshield repair is it has a relatively low entry point. Getting into the windshield repair business, even with great equipment like the equipment GlasWeld manufactures might only cost you say six hundred dollars or so as an entry point to get started with the proper equipment and then you have significant margins with windshield repair. Your typical resin cost is in the neighborhood of say thirty cents to fifty cents on the high end per repair. That means that you can have high margins on the repair work that you do and as we have already mentioned, still maintain relatively low overhead.

What makes GlasWeld windshield chip repair products better than the competition?

Let’s break this into three categories; Injectors, Curing, and Resin. The three main components of any professional windshield chip repair kit or windshield repair kit. So, let’s start by talking about the Injectors. The first thing to notice about all GlasWeld injectors is the power of the ProVac. The ProVac technology, is something that’s integrated into every GlasWeld injector. Meaning that they can sustain a tremendously strong vacuum, in most cases 28/29 pounds at sea level or more while injecting the resin into the break. So holding the vacuum while it’s under the vacuum cycle and then maintaining that vacuum while injecting; without external pumps and external hoses. Creating a significant impact on your repairs, and providing cleaner repairs. Less moisture re-infusion, less air re-infusion, giving you a much better-looking windshield chip repair over the long haul.

In addition to the fact that the ProVac Zoom has our strongest vacuum ever, the strongest in the industry, and it’s able to achieve that vacuum in less than three turns. So it’s really quick, really simple to use, that’s the next point about our injectors. All of our injectors are designed to be really simple to use, especially the zoom, which has very few moving parts. Just take one look at it, it’s just as simple as click, click, click , thread, thread, thread, and then thread, thread, thread. There’s really not much more to it than that as far as the general use of the injector. There’s not any kind of crazy pumps or hoses that have to attach to it. No fancy movements that you have to make one way or another. No set screws to monkey with, cam locks to monkey with, leveling screws to monkey with or anything like that.

In addition to those, our injectors use a tripod rather than a single suction cup stand. Removing the need for additional adjustments and of course, the Z-mount technology which uses tiny ratchet teeth and a spring-loaded tripod stand to mount against the glass in a matter seconds; without any real effort and taking of the guesswork out of how much pressure is too much pressure against the glass.

Now let’s talk about curing, when it comes to curing, flash curing LED technology, the Procur plus is a patented curing light, 360 degrees of simultaneous LED curing all around the break helps to reduce resin shrinkage during the curing process. All LEDs, never change any bulbs, the built-in logo flashing light timer not only looks cool, but really has a practical function, able to cure in 45 to 60 seconds. The fastest curing light in the industry by far.

Now, let’s talk about resin. When it comes to resin, we do a tremendous amount of testing to make sure that we have the very best resin on the market. Through longevity testing, crazing, yellowing, tensile strength, pull tests, etc. All of these tests allow us to verify that our resins not only fill, hide, and make your breaks look great, but that they last potentially for decades. Keeping your repairs intact and looking strong. We have tinted resins to help absorb the fiber optic effect that you have within a break. They’ve got tremendous flowing and wicking properties to allow it into every tiny fissure of the break and hiding features to give you great looking repairs.

So, once again, injectors, curing, and resin. All far superior to the competition and built, tested, and proven to be the best windshield chip repair kit in the industry.

When deciding on a windshield repair kit, the first thing we should look at is technology.

Technology and innovation matters, particularly in the sense that technology allows for you to get an excellent repair even when the situation is not ideal. When climate factors are involved or when you are working with a difficult break. Technology can help you get the air and moisture out. Technology can help get the resin in and flowing. It can help to provide a better-looking repair regardless of the circumstances. So great technology should be your number one priority.

Many technicians make the mistake of buying an entry-level windshield repair kit and then a few months later or a year or two later buy a little bit better system when in reality the difference in cost for that initial investment may have only been 100 or 200 dollars.

The other thing you really should factor in is simplicity. You know, the greatest technology in the world doesn’t matter if you can’t use it properly.

Here at GlasWeld, our philosophy when it comes to engineering is that great technology makes a difficult task simple. So everything we design is with the goal of helping you achieve excellent and consistent results, without creating complex, multi-step processes to get to that point. Looking for simplicity of use is a big factor that’s going to help you get up and running quickly. Ultimately leading to less frustration when you’re out on the job site.

The other factor is training, does the windshield chip repair manufacturer offer comprehensive training. Not just basic training, but extensive training. Providing you the tools to learn how to do more than just a basic rock chip repair.

Do they have a support staff that knows windshield repair? One that you can call when you have an issue with a specific type of repair and have them guide you through the glass repair process. Indeed, that’s something to factor in as well. GlasWeld, of course, has that staff. We have certified windshield repair technicians available to you, who are also our customer support staff. They are there to support you along the way.

In addition, can you get certified? Do they have a certification option where you can take your training to the next level? Those are all things to factor in when looking for a professional windshield repair kit. The other factor is support, do they have excellent customer service available to you? What are the hours that they’re open to you? If you run into a tough break, do you have somebody there to help you with that?

What’s your warranty on your glass repair equipment? Do you have a lifetime warranty on your windshield injector? Is the lifetime warranty indeed a lifetime warranty? How long has the company been in business? What’s their support and track record over an extended period?

Another factor to consider is the longevity of your windshield repair equipment. Will you have to replace your windshield repair kit, every three to five years, or even once a year? Is your windshield repair kit built to last? Is it manufactured with the materials and design to last say 10, 15, 20 plus years?

Many GlasWeld customers are still using their original glass repair kit from say 25 years ago or even more. So those are several things you should consider when you’re buying a professional windshield repair kit.

How long does it take to properly cure a windshield repair with a professional windshield repair kit curing light?

Well, the answer is it depends on the curing light that you choose. If you’ve got our basic CurLite which is just our small little LED curing light, that will take you about three minutes. If you’re using our CurAll, which is more of a standard stick light that also uses LED technology, that will also take you about two to three minutes; by placing it on each side of your bridge as you go through the curing process.

Now with the ProCur+ light, it has reduced the curing time down to about 45 to 60 seconds. The advantage of the ProCur+ is that it can sit directly over the injector and cure all sides of the break simultaneously. It also utilizes flash curing LED technology, to speed up the curing process.

One of the things you might ask is, what is the benefit of curing in as little as 45 seconds? Well, the first answer is that time is money. The quicker you can cure your repairs, the more repairs you can do in a day, and therefore you can increase your productivity and potentially your bottom line.

The other thing to consider is windshield repair shrinkage. Windshield repair resin does shrink as it cures, just slightly, so by curing under pressure and by curing quickly, we reduce or get ahead of as much of that shrinkage as possible; improving the quality of your repairs and of course speeding up the windshield chip repair.

A question you might ask in searching or shopping for a professional-grade windshield chip repair kit or windshield repair kit is, why are GlasWeld products a little more expensive?

Maybe you’re looking at the cost of a base windshield repair kit versus the base kit with others systems on the market. Well, the main reason is the quality. Our kits are built to a whole other level when it comes to quality. Surgical grade stainless steel, high-quality polymers that are built to last and resist for decades; not a few years. Our injectors, many of them are have been in the field for 20-25 years and are still going strong. Talk to our customers, and they’ll attest to that fact.

The other factor is technology. We are continually innovating and developing new technologies to make your job easier. Allowing great repairs consistently, without having to battle your equipment, and making elaborate tasks relatively simple.

You’ll see that when you look at our technology, things that are unmatched in the industry, things like ProVac technology, Z-mount technology, ProCur plus, the built-in timer, the flash curing LED technology, and many others that certainly can affect to a small degree the cost of windshield repair kit.

The other factor to consider is our warranty. Our injectors have a true lifetime warranty, one that we stand behind. We also offer an incredible amount of ongoing support, with an internal staff of customer service reps that are certified windshield repair technicians; providing support for any issues you may have along the way.

GlasWeld has been innovating for over 35 years, and we will continue to do so to ensure that we provide our technicians with the very best windshield repair kit in the industry.

Which GlasWeld windshield repair kit would be the best to start with?

Well, there’s a couple of main factors that we want to break down. First, what’s your budget, and secondly what type of work do you plan on doing?

Do you plan on working in a mobile setting or a shop setting? Do you plan on working on all types of repairs including long cracks, corners, and edges? Do you plan on just doing basic windshield repair; in other words bull’s-eyes, star breaks, combination breaks, and nothing else. If that were the case, we would recommend that you talk to our customer service team, tell them what you, where you do it, and they’ll be able to help point you in the right direction.

If you’re for instance working in a shop setting, you may be able to get by with just simply an essentials kit. Our essential windshield repair kit starts around $600, and it provides you with a high-quality windshield repair kit. Then, you can always add on additional accessories if you need them over time.

If you’re working in a mobile setting, you might consider one of our slightly upgraded windshield repair kit, that has additional accessories. If you’re doing long crack repair, we would recommend that you start with a windshield repair kit that has the long crack extension tool or corner edge tool. Also, utilizing our long crack resins like 2010 gray, or CrackWeld 1000 or 2000, will help you to tackle those types of repairs as well.

How long will it take me to recoup my initial investment if I buy a professional glass windshield repair kit?

Let’s take a look at a conservative scenario for a windshield repair kit purchase. Generally speaking, most windshield repair technicians in the US market, on the low end, charge $45 per repair for retail windshield repair work. That’s what you would bill to your customer or that the insurance company would pay in a worst case scenario in a retail environment. With our Zoom Essential windshield repair kit, which is our entry-level windshield repair kit, a package that includes our latest technology. You would only need 14 repairs to pay for your initial investment. In many markets, the going rate for retail work can be much higher than this rate, but even on the very low end, 14 repairs will recoup your initial investment. In addition to that, our essential kit comes with initial supplies for over 100 repairs. Leaving you with plenty of supplies to not only recoup your investment but turn a substantial profit on your initial purchase.

On the flip side of that, if you were to invest in the zoom pro elite windshield repair kit, with enough supplies to do four to six hundred repairs. In that scenario, it would take you about 38 to 39 repairs to completely recoup your initial investment. In either case, the return on investment can be quite quick. A seasoned windshield repair technician with established customers and routes may do 10, 15, or even more repairs per day. Which is why when you factor in the speed, technology, and quality of repair our windshield repair kit provides, it makes the initial investment that much more beneficial to your business.

First, all of our windshield repair kit injectors are made out of surgical grade stainless steel and carry a true lifetime warranty. Beyond that, here at GlasWeld, we take a great deal of pride in the technology, quality, and craftsmanship that goes into our equipment. We use the highest quality materials throughout our manufacturing process to ensure quality and longevity over the life of the windshield chip repair kit.

The other components to factor in besides the injector are the curing light and accessories. Obviously, our resins are consumable, and you will typically go through those in a few weeks, months, or even a year. Beyond that though, our curing lights and accessories all carry a one year warranty. But because of the level of design and the components we use, in most cases, our curing lights and accessories will last for many years or more.

What sort of warranty does GlasWeld provide on their windshield repair injectors?

The short answer is a lifetime warranty. Now, we’re talking about any manufacturing defect that may present itself over time or a piece that may wear out over time as well. If your threading mechanism or your Z-mount teeth start to wear out, we’ll either repair or replace it. Our warranty doesn’t carry a time limit, and it’s a guarantee we have and continue to, stand behind. Now, of course, this does not cover things like tampering with the injector, unauthorized repairs, or modification that you might make on your end, but indeed, the warranty is built to last.

Now, this would not cover things like the seals inside. The seals are just a consumable that needs occasional replacement, and we also recommend that you use GlasWeld resin’s to keep your warranty enforced for the long haul.

We truly stand behind our warranty. Our original ProVac injectors are still accepted in-house with occasional warranty issues, and we repair or replace those products to this day. It’s a big part of who we are, and it’s a lifetime warranty we will continue to stand behind.

Well, the first thing is our QuickStart guide, included in every windshield repair kit. Its laminated information that shows exactly how to accomplish a proper repair, with with images and instructions. In addition to familiarizing you with the standards here in the US market.

In addition to that, you’ll get a DVD which will have all of the videos which you can watch at home or on your computer. You’ll also have access to our online training, which is available at Feel free to preview that even before you purchase your windshield repair kit.

In addition to that, we offer monthly free in-house training once a month up in our beautiful location in Bend Oregon, so if you feel like traveling to the beautiful Bend Oregon and getting some hands-on expert windshield repair training, we invite you to do so.

In addition to that, we occasionally offer traveling classes around some of the trade shows and such where we may provide some hands-on training, so keep an eye out for that on Facebook and other places where we present news.

Besides that though we offer two things that are unique in our industry. We provide a two-tiered certification platform. Our windshield repair certification platform provides exclusive access to in-depth HD video training. Which is an all-encompassing windshield repair course encompassing everything from understanding the business, repairing complex types of breaks, billing insurance companies, understanding ADAS calibration, and more. You’ll then test your knowledge across various modules resulting in a pass or fail grade at the end. At that point, if you pass, you’ll become a GlasWeld certified windshield repair technician.

Now we also have a second GlasWeld Certified Master Technician tier, and that means that you’ve not only passed the knowledge portion but a practical portion. In this phase, we ship you a small piece of glass and a pop-up stand, which is bar-coded specifically to you as a technician. It’ll have four breaks in it which you’ll have to repair. Upon completion, we will scan your repairs and provide you detailed feedback and a report card on your repair quality. Upon passing, you will then be a GlasWeld Certified Master Technician.

We offer more training options than virtually any other manufacturer on the market, and we do it to ensure that you have the proper tools for success.

Why should you get certified, well the first reason is it does add credibility to your windshield repair business. Indeed, retail customers now are trained to look for certifications in many different industries. Windshield repair is no different, and that would be true also for wholesale customers as well. Now it is true that at this point the insurance companies do not require certification for windshield repair technicians, but indeed, for wholesale and retail customers, it can and will likely matter in your local market.

Also, getting certified can set you apart in your local market. Showing your customers your report card and your skills that you’ve passed a specific test, you’ve crossed a given level, you’ve proven your knowledge, and your skills. Can certainly help to set you apart in comparison to your competition.

Now let’s say you’re a business owner or a business manager, why should you consider getting your technicians certified through GlasWeld’s certification process. The main reason is that it gives you a standardized training platform, which can be extremely valuable for employers with turnover, when technicians can come and go. Windshield repair technicians and glass repair technicians may come and go, but you would have a standard process through which you train all of your technicians, that holds them to the same standard.

They can undoubtedly fail the test, there’s a series of questions that they have to answer, videos they have to watch, and if you go with the master certification platform, they also have to prove their actual and practical repair skills. So certainly doing this can help to provide a standardized process to help make life easier for those business owners and managers out there.

The first thing to be aware of is if the customer has full coverage, in most cases, the insurance company will cover the cost of the windshield repair. However, in some states, there may be an exception to that. In addition to the fact that if they only have liability insurance, the insurance company will likely not cover the cost of the windshield chip repair. So a fallback position would be a cash job or a credit card job in that situation.

So how do you get set up with insurance companies, well the first thing to understand is that most insurance companies don’t handle or receive their phone calls or approvals directly. Almost all insurance companies use what’s called a TPA or a third party administrator. That’s just a company that works for the insurance company, which will receive the phone call, and they may answer the phone sounding like the insurance company, but in reality, they’re a third party that will handle the paperwork side of that claim.

The first thing you would want to do if you ‘re going to do insurance work is to get set up and approved through the primary TPAs on the market, and those may include Harman Solutions Group, Gerber National, Lynx Services, and SGC. There are some others out there, but those four cover the majority of the major insurance companies on the market.

The next question is how do you get set up with those TPA’s, well you would want to contact the TPA either online or by phone and typically they’ll request certain documentation in order to get set up in their system. You generally need a certificate of liability insurance, a fax number, somewhere for them to send information, a w-9 form or a tax identification number for the IRS, and in the case of the SGC network, you probably need a photograph of your business vehicle showing the company name or logo as well.

Once you’ve submitted all that information and receive the approval, you’ll likely get a packet that will give you a shop number specifically assigned to your business. Whether you have an actual shop or not, you’ll get that shop number and a list of set rates, in most cases those prices are non-negotiable, but those are set standards from the insurance company which you’ll get paid on every invoice that you do for customers of that insurance company.

Once you’ve set up that portion of things, then the TPA can help you to do the paperwork side of things. So now let’s imagine that the customer comes to you and you’re about to go through the process of getting insurance approval, how does that work. Now that you’ve done the backend work and you’re set up through the TPAs; you’re able to bill through one of those insurance companies.

Let’s just step through the entire process. First, you would interact with the customer, asking for their insurance card. Tthe back of the insurance card will have a number for approvals. You would then call that number and speak with, in most cases, a TPA agent. Walking them through where the repair is and where the damage is to the vehicle. They may request some information about your shop number or some other information from you. In almost every case, they will require the VIN of the vehicle and any additional pertinent information. If it’s approved, then they’ll give you an authorization number, which you’ll need to include on the invoice. You’ll want to make a note of that authorization number, then complete the repair for the customer, and then you’ll submit that invoice to the TPA.

You have various ways to which you can submit your claim. Some TPAs have an online service, a fax service, in some cases an email service, or you could also use an EDI (digital processing platform). There are a couple of different EDI companies out there that charge you, per claim, to process and submit to the TPAs.

That covers how to get set up with insurance companies, first understanding that they primarily work through TPAs. Second, getting set up and approved by those TPAs. Third, understanding the steps to obtain authorization for each claim from those TPA’s. And lastly, submitting your final invoice to the TPA’s.

That’s a loaded question, every market is different, whether you’re in the US or whether you’re in another country. So the first piece of advice is just to do your research, make some phone calls and find out what your competition is charging to better understand your local market. Do the local insurance companies provide complete rock chip coverage? Is there a windshield chip repair deductible involved? Understanding those factors will help you to set your pricing locally.

However, let’s focus in for a moment on the US and Canadian market and just talk about kind of how to set your rock chip pricing in those markets. Now we would break this into say three categories when it comes to pricing. One would be retail work, another would be wholesale work, and the final would be insurance work.

Retail work would be cash jobs directly for a customer. Kind of in a one-off scenario and generally speaking, the going rate in the U.S. is $65 or more. When it comes to retail work, especially if it’s mobile rock chip repairs, that may even go up to $75 to $100 depending on your area. Again, you want to do your research in your local area.

When it comes to wholesale work, we would be talking about fleet accounts, dealership accounts, body shops, or car washes. These places would be providing consistent volume work, for which you would then offer them a discounted rate. For instance, forty-five dollars or even less depending on the volume of work that they provide. Again, do your local research, find out what the local fleet accounts are currently paying for windshield chip repair and base your rates around that accordingly.

Now the next category is insurance work. Insurance companies set their prices specifically for professional windshield repair. Meaning you don’t have a whole lot of control over what they pay for the windshield chip repair. Generally speaking, most insurance companies will pay between forty-five dollars up to about seventy dollars on the high end for the first rock chip repair, and then typically they will pay an additional fifteen to maybe twenty on the high end for a second repair on the same vehicle. So that’s a good rule of thumb to be aware of when you’re doing insurance work.

As far as doing second repairs on retail and wholesale work, generally you would have a second, slightly lower rate, for a second or third repair on the same windshield.

Now again, in regards to international markets, it’s crucial that you research your local area. Do some research, determine what the factors are in the area. Is the glass readily available? Do insurance companies cover the repair? Are there other windshield repair technicians in the area? If so, what level of work are they doing? What quality of work are they doing? What are they charging? Then using all this information to set your rates accordingly.

How do I address repairing a vertical windshield? Let’s say it’s a recreational vehicle, semi-truck, or maybe even the sidelight of a vehicle where the injector needs to be pretty much horizontal to the glass on a vertical piece of glass?

The first thing to understand with vertical glass windshield repair is that to achieve the proper vacuum and resin pressure; you need to have a slight downward angle to the glass. This downward angle allows the resin to flow correctly into the break as well as the vacuum to achieve the proper suction to clean the break of moisture and liquid needed for a high-quality windshield repair. So it is critical to first get the correct angle to for your injector.

With the tripod stand design, you’ve got the ability in vertical glass scenarios to adjust the suction cup depth. By threading the lower suction cups out, you are able to adjust the pitch of your injector, therefore allowing you to get a proper vacuum and do the repair. That’s the simplest way to address vertical glass using any of our windshield repair injectors. Now, in particular, this works well with the new ProVac Zoom because it has a thicker and softer seal, which helps to compensate a little bit for that extra angle. You may want an additional click when working on a vertical glass, just to make sure you have a proper seal on the glass, before your vacuum and injection cycles.

Beyond that, GlasWeld does offer an adapter that goes between the injector and the glass itself, and that adapter has a slight taper to it which can help to provide an additional tilt. You could use this in conjunction with kicking out the suction cup or instead of that. We’ve got several options for you but really, repairing vertical glass with a ProVac Zoom or with any of our windshield repair kit injectors should be no problem if you follow those steps.

What is the difference between pit filler and chip filler resin that GlasWeld sells?

Well, pit filler resin was explicitly designed to fill the impact point of a rock chip. So. when the impact is on the surface, and there’s a break underneath that surface, then that’s when we would use the pit fill resin after completing the repair.

Now the chip fill resin is a little bit thicker and has a little bit better adhesion. It’s designed for surface pits or surface impacts, where there’s not a break underneath it so that the impact point doesn’t go very deep. That’s where you would use the chip filler. The chip filler can also be used if you’re doing repairs on plate glass, on edges, or different types of creative scenarios where you may need to replace a piece of glass that is scalloped off the edge. It’s a little bit thicker, a little more moldable, to allow you to deal with those types of scenarios. Indeed we do have some customers that like chip filler, rather than pit filler, even for doing their standard pit fills after repairing.

Now the next question is, why should you use a pit filler or chip filler resin instead of just a standard windshield repair resin for that last and final step when you go to fill the impact point? Well, the main reason is the chemistry involved. The resin used inside the break has different properties, it’s designed to flow, it’s designed to hide, it’s intended to bond and hold the glass together. However, it is not necessarily designed to last as long against direct sunlight, direct heat, direct saltwater, moisture, and everything else. Whereas chip filler is intended to avoid yellowing, crazing, it’s primarily designed to seal off that break as best as possible and keep it looking great. So, that’s the main reason why you would want to use a pit filler or a chip filler as the last and final step of your repair rather than a conventional windshield repair resin.

What do I do when I run into a break that’s got a lot of dust or debris or rain-x that’s accumulated over time? How do I handle that, is it repairable, etc.?

Well, the short answer is yes in most cases it is repairable, but the first thing you need to do is to understand and identify the issue. So, close inspection of the repair is critical. Determining to what extent, maybe asking a few questions about how long it’s been there, and then creating the proper expectations for your customer. Theirs no appropriate and recommended way to remove debris from the inside of the break, in all of the tests that we’ve done with the products on the market that are injected into the break, we found that they can have structural integrity issues when inserted into the break, affecting the polyvinyl butyrate. So, here at GlasWeld, we don’t recommend injecting anything into the break before doing the break due to those potential liability issues.

The most significant thing you can do is communicate with your customer, if theirs a lot of dirt and debris in the break, create the proper expectation that it may be a little more visible then it usually would if the break had occurred a few days ago or even a few weeks ago. Especially when theirs a lot of debris inside the break.

If you determine that there is rain-x inside the break, that’s another factor. You can certainly attempt to repair the break, but it would be good to communicate to the customer that in some cases you just don’t get the proper adhesion between the windshield repair resin and rain-x. Even after injecting the break with a product that is used specifically for that, it’s our experience, that in most cases or some cases that the repair will still fail. So, indeed you can repair breaks that have dust or debris in them, but creating the proper expectations for your customers and communicating with your customers is critical.

What causes a windshield repair or break in the glass to spread, in other words, a break starts out as a small bullseye or combination break and then turns into a long line that may become unrepairable. So, what factors are there to cause that?

Well, the most significant thing is a change of temperatures, especially in climates or times of year where the temperature swing between the night and morning. Or, between the time when you pull your car out of the garage and when you start driving down the street. There could be a drastic temperature swing, in particular, in states like Arizona where at night it’s freezing and during the day it’s scorching. Those temperature swings create a tremendous amount of expansion and contraction within the glass itself, which puts an enormous amount of pressure on those weak spots. Especially in the area where the glass windshield was broken, temperature swings are the likeliest cause for a break to spread over time.

The other thing is just flexing, as the windshield is flexing and moving constantly. As a vehicle moves, it is continuously flexing & twisting, especially in parts of the country where there’s a lot of potholes or rough roads in general. That constant vibration, twisting, and flexing can cause a break to spread.

Certainly, an excessive amount of pressure by the injector against the glass can cause the break to spread. A suction cup that applies too much pressure to the repair area, causing a leg to spread. Some other options include excessive resin pressure, injecting too much resin, injecting the resin too fast into the break, or not cooling the glass down to a proper temperature before starting a repair; all those things can cause a break to spread during the repair process.

Of course, the GlasWeld ProVac Zoom helps to alleviate a lot of these issues the Z-mount system helps to prevent you from over tightening it against the glass. The new seal helps to absorb excess resin pressure, reducing the flowering effect, as well as the possibility of excessive resin pressure, which can cause a crack to spread. But, of course you still want to try to get the glass down to a moderate temperature before starting your repair even when using the ProVac Zoom.

How many rock chips can you repair on a windshield before having to replace the glass?

Well, the short answer is there’s no set number, it really has to do with the quality of repair work that was done. An excellent rock chip repair will be less visible than a smushed bug on the windshield. In fact, in some cases it will look just like a little opaque water spot on the glass. So, if the repair was done correctly, in other words, all air and moisture were removed, resin completely filled, and completely cured without shrinkage; then the repairs may be relatively or close to invisible.

So, the short answer to that is if you use great equipment and you run into a windshield, for instance in a fleet account. You’ve repaired this once, or maybe multiple times; you’ve done the repairs correctly. You’ve used an excellent professional windshield repair kit, great resins, a proper curing process; then you may be able to repair that windshield dozens of times. However, if the windshield has been repaired improperly multiple times over the past, it may be a windshield you choose just to replace.

Another really common question we get here at GlasWeld is about tinted resins; when to use them, what they do, and when to use which tint?

Let’s jump into those questions, first off, what do they do? Well, they’re designed to help absorb light reflection and light refraction. Essentially minimizing the fiberoptic effect, in particular, with breaks that have legs that radiate off of the break. A combination break, particularly in tight star brakes or long cracks, the tint can help to absorb the light refraction, therefore, reducing the visibility of the crack to the human eye.

The next question is when to use them, and when to use which of them. Our Amber is probably our most popular; it tends to be used mostly on combination breaks. So, that’s one and you can also certainly use that on bulls-eyes. Our gray is excellent for tight start breaks and short, long cracks. I love our 2010 gray; it’s probably one of the first resins I pull out for 50% or more of the breaks that I run into. In fact, I even use it on a complicated combination break that has a lot of crushed glass in the middle or a lot of legs that radiates longer than you would typically see on a combination break. When it comes to clear, usually we would only use clear on a real clean and pure bullseye. When it comes to the green resin, we would typically just use that up in the UV band portion, the upper portion on some vehicles where they have that UV band of tinted glass on the top.

The other thing to consider is viscosity, in the various tints that we offer, we have different viscosities for different temperatures. If it’s a colder climate or a tighter break, you want a thinner resin (2010 All Weather). If it’s a very hot climate or a real open break, you might want a slightly thicker resin (2020 Warm Weather).

How long does it take to do a proper and quality windshield repair?

The answer is, well, it depends, it depends on the type of break and the conditions in which you’re working, but as a general rule of thumb if you’re working on a real clean bullseye break, those can take as little as five minutes. They could take all on up to say 20 minutes or more but in most cases, five to 10 minutes is more than sufficient, if you’ve got a nice clean, perfect bullseye. As we all know, that’s probably not the typical kind of break that you’re running into.

Combination breaks are probably the most common type of break out there, a combination of a star break and a bulls-eye. Combo breaks generally will run you about 10 minutes to 25 minutes.

When it comes to star breaks, those are generally in the 10 to the 30-minute range using GlasWeld equipment.

When it comes to long cracks, typically, between 15 minutes and 45 minutes depending on the length of the crack and the skill level of the technician.

Now, there are other factors to consider, in particular temperature. If you have to spend additional time moderating the temperature of the vehicle, getting the glass to a temperature where it’s workable, that can add additional time. If it’s too hot or too cold outside, that can add a little bit of time to your repair process. Also, setting things up and getting the glass ready to repair, that can also add additional time.

Now, if the glass is frigidly cold, yes you can add to these time frames as well. Heat sometimes will help to speed up the repair process provided that you’re careful about what you’re doing. Also, the GlasWeld zoom ejector was designed for speed and efficiency, with a quicker mounting time, speedier threading action, and a much stronger vacuum. Those features help the Zoom cycle through more complicated repairs and get a faster fill, so you’re not doing multiple cycles like you would with a more basic windshield repair kit on the market.

Finally, using tools like the ProCur+ UV curing light, can cut your repair time by as much as five minutes. Using it’s flash curing properties, it can cure the resin in as little as 45 seconds. Compared to 5-7 minutes with most traditional fluorescent curing solutions out there.

Is it hard to make it in the windshield repair business?

Well, just like in any other business, quality matters. So carrying a level of determination and hard work can go a long way. Also, establishing a good business plan can go a long way. The great thing about windshield repair is that you have low overhead, the initial investment is relatively low, and your costs of material is small. It doesn’t require that you stock an extensive inventory of materials or supply supplies in a shop setting, and you have a relatively low cost per repair. The set-up time is minimal, and the time that it takes to learn the craft and do great windshield repairs is rather quick. Typically, in a few days of practice, and going through our extensive library of online training videos or possibly getting certified through our comprehensive certification platform; you can get comfortable and confident enough to then go out and start doing repairs in the field.
