This auto windshield repair kit is designed to provide owners with the necessary information and tools to repair small damage to laminated auto glass windshields. The liquid has a shear strength up to 25PA, non-yellowing resin, five times stronger than glass. The kit is easy to use and allows anyone to perform permanent airtight repairs on most windshields. It can quickly and effectively repair chips and cracks, bullseyes, spider webs, stars, and scratches in 20-30 minutes. The unique vacuum design prevents air from entering the gel and affecting the repair results.
