Our windshield repair kit contains UV glue. It can seamlessly connect cracks, and the effect is long-lasting. The method of its use is simple: first, clean and dry the damaged area of the windshield, then squeeze the windshield repair fluid into the crack, glue it to the curing film, cure quickly in the sun for 5 minutes, and then clean the surface with a scraper. And the adhesive has strong bonding force to ensure the stability of the repair site.
