How to Repair a Cracked Car Windshield?

[LaPeyton]

Methods for repairing a cracked car windshield: 1. Use a vacuum injector with a syringe-like structure to remove air from the glass crack; 2. Fill the crack with a glass repair agent and perform several rounds of suction and pressure treatment; 3. Use a UV lamp to irradiate the area for two minutes in all directions to solidify the repair solution; 4. After removing the machine, there may still be a small gap at the center of the crack. Apply a higher concentration of repair agent, cover with a glass piece, and irradiate again with the UV lamp to dry. Then, use a blade to level the surface, apply a polishing agent, and polish with a cloth. Once repaired, the windshield generally won’t crack again or suffer other issues unless subjected to secondary impact.
