As a veteran driver with over a decade of experience, I've had my windshield chipped by stones several times. Repair is definitely feasible, especially for small cracks smaller than a coin or star-shaped cracks, as long as they're not in the main viewing area. Professional shops use resin injection for repairs, which takes about half an hour and costs around a hundred yuan. The last time I had it repaired, it lasted two years without spreading. The key is not to wait too long, otherwise, dust can get in and make repairs difficult. If the crack exceeds the length of a bank card or the edges are splitting, it's better not to bother and just replace the glass for safety.
One rainy day, I suddenly noticed a crack on the windshield and rushed to the repair shop. The technician used a UV lamp and resin tools to fix it, much like a dentist filling a tooth. The whole process was fascinating to watch, but it required high skill—the resin had to precisely fill the micro-cracks, and after curing, it restored about 80% of the strength. However, upon close inspection, traces were still visible after the repair, so it's not recommended for large damages. For daily maintenance, avoid sudden temperature changes, and don’t pour cold water directly on the windshield in summer.
