Windshield scratches can be repaired using the following methods: 1. For small and shallow scratches, they can be removed through polishing; 2.

I've noticed many friends asking about windshield scratches. Actually, you can determine repairability by checking the scratch depth. Those fine hairline scratches can be completely polished out - I use professional equipment to remove the surface layer of glass, making it crystal clear like new. Medium-depth scratches can also be fixed by filling with resin and then sanding smooth. However, if it's deep enough to catch your fingernail, it's basically hopeless - forcing a repair might actually cause the glass to crack. My advice: don't attempt DIY fixes, just spend 100-200 yuan at a professional shop. Important reminder: windshields have an inner UV-protective coating - using sandpaper recklessly will damage this coating and further impair visibility.
