How to Repair Scratches on the Car Windshield?
2 Answers
There is only one method to deal with scratches on the car windshield: polishing. Since glass is a highly transparent and very hard material, ordinary scratch wax cannot remove the scratches. Special glass polishing paste is required for removal. Additional information: 1. Depth of scratches: Not all scratches can be repaired. Light scratches can be completely removed, while deep scratches are not recommended for repair because the glass is too thin to withstand deeper abrasion, which may cause the glass to become concave and distort the view. 2. Professional repair shops: It is best to seek specialized shops for glass scratch repair. First, because they have the necessary tools, and second, because glass polishing carries risks. The continuous friction between the polishing disc and the glass generates high temperatures, and if the temperature exceeds the glass's tolerance, the glass may crack.
I've been repairing cars for ten years, and windshield scratches need to be handled case by case. Minor shallow scratches can be fixed by yourself—just slowly polish them with automotive-specific polishing compound. Regular toothpaste isn't stable enough for this. Deeper scratches are trickier; they require resin filling. First, clean the scratched area thoroughly, apply the adhesive, then cure it with a UV lamp, and finally polish it smooth. For tools, I recommend a professional glass repair kit—you can find a basic set online for around 30-50 yuan. Be careful not to let dust get in during the process, or it may leave unsightly air bubbles. If you can't handle it yourself, don't force it—visit a professional auto repair shop or 4S store. They have complete tools and skilled technicians, and the cost is usually around 300 yuan. I always remind car owners to address scratches early, especially in winter when temperature fluctuations can easily turn them into cracks.
