It can be repaired. Here are the methods for repairing the front windshield: 1. Alcohol and Glass Cleaner: Clean the area to be repaired, and after drying, remove any impurities that may exist in the crack. 2. Observation Board: Attach an observation board to the inside of the front windshield to see the repair more clearly. 3. Suction Cup: Align the center point of the suction cup base with the position to be repaired and secure the four corners. 4. Pressurization Device: Fix the pressurization device to the suction cup base, ensuring the position is correct, then unscrew the upper part to pressurize. 5. Repair Fluid: Pour the repair fluid into the opening at the top of the pressurization device, then screw the pressurization rod back into the base. 6. Pressurization Rod: Wait for the repair fluid to penetrate and solidify, which takes about 10 minutes, then unscrew the pressurization rod, wait for a minute, and screw it back in to remove air from inside the crack. 7. Repair Device: Finally, remove the repair device and scrape off any residual repair fluid with a blade.
I've been driving for over a decade and have encountered windshield cracks caused by stones several times. Last month on the highway, it happened again—a star-shaped crack about the size of a fingernail appeared in the lower right corner of the windshield. I immediately drove to my trusted repair shop. The technician used a suction cup to secure the cracked area and slowly injected transparent resin into it with a syringe. After the resin filled the crack, it was cured under a UV lamp for about ten minutes. Amazingly, after the repair, only a tiny white spot the size of a grain of rice remained, completely unnoticeable while driving. The key is to act quickly—I went as soon as the crack appeared. If I had waited a couple more days and the crack spread beyond 20 cm, it would have cost over 2,000 yuan to replace the entire windshield. Now, commuting daily on the ring road, the repaired spot hasn’t changed at all.
