Frequently Asked Questions

What makes your system better than the others on the market?

Well, the first answer to that is speed and ease of use. When it comes to general production scratches, no other system will remove scratches faster than the Gforce system and leave near perfect results. In a production setting, even with advanced optical testing equipment, it will be tough to find distortion after a repair with our Gforce scratch removal system. So definitely that’s one of the significant advantages; faster, easier to use, and also can be used in a shop setting or job site.

It’s built to be mobile, so you can stick the water bottle right on your hip or directly on the glass, go out to the job site, and get some work done. Lightweight, not bulky, some of the systems out there weigh 10 or 12 pounds or more. The Gforce system is under five pounds, so it indeed allows you to get into many different places and work in a vertical setting over an extended period if needed.

Our patented wet process also will enable you to keep the glass at the proper temperature. Maintaining an appropriate flow of water on the glass without having to hold an external water bottle while holding the device at the same time. Those are some of the advantages of the Gforce system.

In addition to that, now with the Microforce disks, it can remove scratches any depth of scratches in almost any scenario, so that’s another big thing. Having a system that will cover the full gamut of scratch removal and do so in a straightforward fashion is what makes the Gforce scratch removal system so great.

What type of scratches can I remove using the Gforce glass scratch removal system? The short answer is almost any type of scratch. Now the Gforce polishing process can be used for really any production scratch, any incidental scratch damage that might occur from glass on glass, aluminum on glass, or even some other scenarios out there like sandpaper scratches, and things of that nature. All of those types of scratches can be removed in a relatively short period of time with little to no distortion, in most cases no distortion, using the Gforce polishing process. Now if you’re using the Microforce disks, now you have expanded to a whole new world of glass scratch removal. Everything from deep graffiti removal caused intentionally on glass, acid etching, to kind of a middle ground which is construction grade scratches. You know on a job site, deeper razor blade cuts, things of that nature. Also, deeper sandpaper scratches and scratches of that nature can be removed using the Microforce disks.

What is the preferred type of glass to remove scratches from?

Well certainly, the Gforce system will work on virtually any flat type of glass; tempered glass, laminated glass, mirror glass, Gorilla Glass, the list goes on and on. The only areas where you can’t use the Gforce system is on some textured glass or on a coated glass where the coating is on the surface that needs to be polished because naturally, the Gforce process would likely remove the coating in that area. So those are kind of the things to keep in mind.

Now as far as the preferred type of glass, tempered glass is by far the easiest to work with. The reason being, tempered glass interacts well with the Gforce system. The Gforce system employs a little bit of heat during the process, and tempered glass can take a higher amount of heat without damaging the glass. So with tempered glass, we can bear down a little bit more on the machine and heat the glass up a bit more than we would with other types of glass. Therefore the scratches come out a bit faster, and also there are just fewer factors involved. We can be less careful when it comes to how much pressure we apply and be a little more aggressive with our approach when it comes to polishing tempered glass.

Will the Gforce glass scratch removal system cause distortion?

The short answer is if you’re using the patented wet polishing process with the Gforce polishing compound and the Gforce polishing disks and you operate it correctly you will not have any optical distortion. Now, of course, there are extreme incorrect manners in which to operate it. If you’re running the disk on edge for a prolonged period or if you’re using way too much compound or way too much heat; you can create some distortion in the glass over time. But, if you’re using it correctly to polish scratches, you will not have any optical distortion. The lack of distortion is one of the reasons why the Gforce system is so widely used in the glass manufacturing and distribution setting.

If you are getting into deeper scratches, things that were caused more on a construction grade or things that were caused maybe by sandpaper or something to that effect, well that’s when the Microforce disk generally would be brought into the process. If you’re using the Microforce disk, you definitely can create distortion, although the Microforce disks are very good at mitigating that to a significant degree due to the cushioned nature of the abrasive. To help you to avoid distortion as much as possible with the Microforce disks, if you’re dealing with pretty deep scratches, with a little-scalloped edge or kind of a shimmer to them; those types of scratches generally would be a little bit deeper. Using a three-inch disc, can help to dissipate distortion or in the case of really deep scratches a 5-inch disc; those discs can help dissipate any optical deviation.

Of course, if the scratch is deep, you might want to work a more extensive area on your first and second steps. If the scratch is not very deep, you will work a little bit shorter of an area or a bit smaller of an area. The other thing you would consider is working across the scratch as if you were walking across the glass rather then up and down or circularly to avoid kind of a coke bottle effect in the glass. Keeping that in mind and understanding how the glass will be placed, and how it will be installed. All those aspects certainly will help to reduce the visible distortion.

Skilled technicians utilizing the new Microforce disks get almost zero optical distortion; however new technicians may get more. So, as you get more experience with the Microforce discs, generally speaking, you’ll be able to reduce your optical distortion substantially over time as you learn how to operate them flat, as you learn how to do overlapping passes, and as you learn how to feather your edges more efficiently.

How deep of a glass scratch can I remove?


The first thing to understand is that depth is usually not the issue. It has more to do with the quantity and length of the scratch, then the actual depths of scratch being removed. The Gforce polishing system allows you to remove most typical production scratches in a relatively short period of time. In addition to that, our new Microforce deep scratch removal disks will enable you to take out deep scratches with relative ease. Between the two, you won’t find many scratches you can’t remove within 15 to 20 minutes.


From a technical standpoint, our Gforce polishing system has been proven to remove scratches distortion-free up to four-thousandths of an inch. Which is generally speaking a relatively deep production type scratch, glass on glass, type scratch. Far beyond that of course, could be removed with the Microforce discs, be it in a production setting or in a construction setting. Again, the depth is not the issue; it’s more about the quantity of scratches when it comes to whether or not you want to accept. For situations where the piece of glass has 10, 15, 20, even 30 scratches on it, it may be more feasible just to discard the glass.

Once you have decided to remove the glass scratch, the next step would be to determine what method is the right one for the glass damage. The Gforce scratch removal kit comes equipped with both polishing disks and Microforce deep scratch removal disks. A good rule of thumb is to run your fingernail over the glass scratch. If your fingernail can feel the scratch but can pass over the scratch without your getting physically stuck in the scratch, those would be considered light to medium. If when you run your fingernail over the glass scratch, it gets stuck, those would be regarded as medium to heavy damage. 

For light to medium glass scratch damage, the Gforce polishing disks would work great and would provide you visibly distortion free results. The medium to heavy is where you would most likely want to consider our Microforce disks. Microforce disks, unlike our polishing disks, are an abrasive, meaning you will be removing glass at a much more rapid pace. By doing so, you are bound to be introducing some level of distortion. So be sure to follow our guidelines and training to mitigate distortion to the glass.

How long will the average scratch removal take?

Well of course it depends, so let’s focus first on the Gforce polishing process with the polishing compound and the polishing disks. In a production setting, which is where the majority of the Gforce customers sit, in that general situation. Light to medium production type scratches, glass on glass, even a relatively deep glass on glass scratch, five to fifteen minutes is generally an appropriate range of time that you would budget for that type of scratch.

Now, if you’re getting into something that’s got kind of a shimmer effect to it or scalloped edges, then budget a little bit more. If it’s like a real tight razorblade scratch, generally speaking, those can take about ten to twenty minutes to remove with the polishing process.

Now if you’re doing deep scratch removal with a Microforce disk. Generally speaking for one scratch area, you’re looking at about ten minutes for a very skilled technician up to about 20 minutes for a new technician to go through the entire glass scratch removal process. Of course, if you’re working on a large piece of glass, where there are many scratches, of course, those time frames will be doubled, tripled, or even quadrupled depending on the number of scratches and areas you have to work.

How long do the disks, the compound, backer pads, and Microforce disks last?

So let’s start with the polishing disks for the Gforce system. The Gforce polishing disks generally last about 20 to 25 hours of on the glass polishing time. So we’re talking about time where you’re actually operating on the glass itself. Now of course with any of our products, be it the compound, the disk, or the backer pads, they’re going to be significantly affected, or the life will be substantially affected if they’re running improperly, in particular, if they’re run up on edge. The edges certainly will wear the disks out more quickly, it will kind of round out the disk, and and it will undoubtedly wear out much faster.

With the Gforce polishing disk, if you run the machine correctly, you’ll get about 20 to 25 hours of use out of each disk. The disks are sold in three packs so more or less you can calculate that is about 75 hours worth of polishing if you’re using the system correctly. Those disks should wear pretty evenly all the way down until they’re pretty much wafer thin. That’s when you would want to pull them off, replace them, and put a new disc on to continue doing scratch removal.

Now the compound dovetails into that nicely because generally speaking, you
should get about 75 hours of polishing out of one jar of compound. So generally speaking if you’re buying consumables think in pairs, a pack of three disks to one jar of the compound more or less equates to an equal consumable time for those two products. Now when it comes to backer pads, they can last anywhere from a few months to several years depending on your usage and how often you’re doing scratch removal. If you’re doing it once a month just as kind of an incidental type of thing, they could last you a few years. If you’re using them every day, two or three shifts on a production line or something of that nature, then they may only last you three to six months. Of course, again, running them on the edge will greatly reduce the life, so one of the things you can check with your backer pads is to look around the perimeter of the backer. See if it’s starting to wear out on the edges first. If it is, it may be a sign that your technique or you yourself may be running it slightly on an edge and that’s something you may want to try to correct to reduce your consumable costs over time.

Now let’s talk about the Microforce disks and how long they’re expected to last. Keep in mind that the initial disk that you use to actually remove the scratch is doing the majority of the work, so with the 180 or the 360 would typically be what you would use for the first step depending on the depth of the scratch. Those are going to wear out a little bit quicker than the 500 or 1000 disks that are used more to polish up the surface. So you might expect somewhere between three to five repairs out of your typical first step discs. So, in other words, three to five scratches, especially deeper scratches to fully remove the scratch. Make sure you clean them properly as we show in our training video, using water or a brush to get all of that kind of glass dust out of them, and I that will extend the life of them. Again, like we mention with the other disks, running on that the proper temperature and not running them on an edge; all of those things will help to extend the life of the disk so you can continue using them as long as possible.

What is the learning curve, how quickly can I pick it up and go out and do work?

For most technicians, it’s between 2 and 4 hours of practice time will get them to the point where they feel comfortable working on a piece of glass on a customers vehicle. Indeed, if you’re working in a controlled environment, for instance, a production setting on a shop floor, where you are working on a table; the learning curve can be as short as thirty minutes to an hour.

If you’re working on a windshield of a car, a sidelight, or in a building, the learning curve is going to be a little bit steeper. You will want to get proficient with the system before actually starting to work on a customers vehicle.

We would recommend getting yourself a piece of glass, putting it in your warehouse, in your shed, or where ever it might be. Scratching it up and practicing for a few hours minimum, getting comfortable with the process and the techniques before you begin working on a customers vehicle.

The technique is what’s most important, so following our training videos and working on your technology is the crucial factor in being as efficient and productive in a live setting.

You can absolutely learn how to use the Gforce scratch removal system without having hands-on training. Of course, hands-on training in the scratch removal industry and any industry is always a great benefit. We offer monthly free training courses at our facility in Bend Oregon, as well as at some of the trade shows around the world. That is always a great benefit to technicians, having a couple of hours of training with a skilled technician can go a long way, but for you and your business, this may not work.

So, in addition to that, all of our kits include a comprehensive training suite included in your kit. We also offer a full digital library of training videos and content that cover everything from the technique, to pressure, heat, and more. The one advantage of using our visibly distortion-free glass scratch removal equipment is that as long as you are starting flat on the glass and utilizing your body to keep the polishing disk flat on the glass, and working with the machine rather than against it; you are going to see excellent results every time.

Another very common question we get about the Gforce glass scratch removal system is how much should I charge for glass scratch removal? 

If you’re asking that question, it’s likely that you’re doing work for a job site, a construction company, or maybe you’re a glass shop wanting to offer glass scratch removal services to your customers. Generally speaking, you want to set a minimum fee that will cover up to one hour worth of work once you arrive at the job. That should cover you whether it’s one single scratch or a couple of small scratches. By doing that and having an hourly rate beyond your minimum fee, that covers you for situations where the customer might call you and tell you “hey I’ve got one glass scratch” only to arrive at the job site and there are fifteen scratches. Yes, you would want to be able to be flexible on those types of scenarios. 

Our suggestion is somewhere between 65 and 150 dollars per hour, with a minimum fee. Many glass scratch removal technicians charge $100-$125 for their minimum fee and then have an hourly rate that’s comparable to that or maybe slightly less for any additional hours. Generally speaking, this will help you to avoid situations where you go all the way out to the job site for some inexpensive piece of glass, and you have to spend two hours on it to remove one scratch. 

Having an hourly rate will be appropriate and will help prepare your customers for what’s involved in doing extensive glass scratch restoration if that were to become the case. There might be some cases where you would bid on a job, let’s say you’re looking at a large installed piece of glass. You can see the scratch clearly; there are one or two visible scratches. You know exactly how long it’s going to take you to remove the damage, exactly what’s involved, and those may be situations where you would bid the job in advance at a specific price.

Can or will insurance companies approve billing a glass scratch removal, particular on a windshield due to some damage to the windshield? Indeed, it depends on the insurance company. Some insurance companies may approve, others may not, so we would recommend you seek the approval, call the number on the back of the customer’s insurance card before repairing to verify that they will cover it. It’s probably not something that’s standard practice for insurance companies, so it’s something you would want to try to get the approval on before doing the work.

What’s the warranty on the Gforce system? Well, the short answer is it’s a one year warranty that you get with your Gforce system. It covers all the parts, not the consumables, but all the parts. It includes the primary components of the tool and the water feed system as well. So if you have any manufacturing defects or issues over that first year, things that just aren’t working correctly, we will warrant those provided that it wasn’t caused by excessive abuse to the system itself. Indeed, if that is the case, give our customer service team a call, and they can step you through any and all possible issues that you may encounter and make a determination as to whether we can replace an individual part or whether we need to replace the whole system.

Do I need the center water feed system or a water feed system at all? The short answer is you don’t necessarily have to have it, but it makes the process so much easier. Imagine running a relatively small tool that has a lot of torque and a lot of speed with a small disc and then having to hold a water bottle separately. It’s no easy task. Indeed it can be done, skilled technicians do it all the time, but that’s where the Gforce patented water feed system comes into play. It makes the process so much easier for you to get out on the job site and do a proper repair in a timely fashion, without struggling through the repair by having that built-in water feed system.
