How to Repair a Crack in the Car Windshield?
1 Answers
Methods for repairing glass cracks include: 1. Purchase specialized products for repairing glass scratches. Mark the area to be repaired with a pen, then use strong light to observe the scratches on the glass. Apply polishing paste to a wool wheel and evenly spread it over the repair area. Start the angle grinder for polishing, spraying some water every 15 seconds and allowing 20 seconds for cooling. Finally, wipe off the polishing paste with a damp towel to complete the repair. 2. For more severe scratches (such as burns from welding slag or scratches from stones and sand), begin with a No. 1 grinding disc for coarse grinding. Attach the No. 1 grinding disc firmly to the backing pad. Adjust the variable-speed angle grinder to the second gear and start grinding. Ensure full contact with the glass. Once the scratches are completely gone, the repair process is complete. 3. If the scratches are extensive, take the car to a professional technician at an auto beauty shop for repair. If the crack is too long, it is recommended to replace the entire windshield.
