Quality resin is the key to safe, durable, and better-looking windshield repairs. When repairing cracks 6 inches or longer, you need a resin specifically designed to handle the challenge.

Crackweld is available in two viscosities (1000 and 2000).

The purpose of long crack repair is simple: Disguise the crack and restore the safety of the windshield.

The catch? Without quality resin, it’s impossible to accomplish either goal. You can have the best tools and the best skills, but if you’re using cheap resin, your repair is compromised.

Resin is important. GlasWeld premium resins are…

  • Formulated for maximum clarity and strength (up to 34% stronger than other leading brands)
  • Independently-tested to meet and exceed national and international industry standards, including ANSI, NWRA, BSI, and AS/NZS

Long Crack Repair Resin is specifically designed for repairing cracks. Each 10 ml bottle has enough resin for approximately (10) 10-inch repairs.

This is not a stand-alone product. It is intended for use with the Zoom injector and ProCur+ curing light.

Long Crack Repair Resin is available in two viscosities.

  • Crackweld 1000: Crackweld 1000 is perfect for use in environments with moderate temperatures.
  • Crackweld 2000: Crackweld 2000 is perfect for use in environments with extreme temperatures.

If your area experiences large temperature swings at any point during the year, Crackweld 2000 is the way to go.
