Our car windshield repair drops contain UV glue. They can form a protective layer to resist daily wear and tear. The usage method is very simple: clean and dry the damaged area of the windshield, apply the windshield repair agent to the area that needs repair, attach the curing film and let it cure quickly under the sunlight for 5 minutes. Finally, use a knife to clean the remaining resin on the surface. This can effectively prevent the expansion of small cracks, extend the service life of the windshield, and after the repair, the glass will have no obvious marks and maintain its original transparency.
