What to Do If Car Glass Cracks?
2 Answers
Solutions for cracked car glass: If the glass only has a small scratch, you can use glass repair agents, also known as polishing compounds, along with some sandpaper, a disc, and a polishing wheel to fix it. However, remember that this process requires patience—do not rush to avoid creating deeper marks that could make the glass irreparable. Car glass is manufactured by heating the glass in a furnace to near its softening temperature, then quickly transferring it into air grids with varying cooling intensities for uneven cooling. This process creates different stresses between the main viewing area and the peripheral areas of the glass. There are mainly three types of car glass: laminated glass, tempered glass, and zone-tempered glass.
I've been driving for many years and have encountered windshield cracks several times, usually caused by flying stones or impact objects on the road. Safety always comes first: untreated cracks can quickly expand, especially during temperature changes or on bumpy roads, potentially causing the entire glass to suddenly shatter, severely affecting driving visibility and even injuring people inside the car. My experience is that once a crack is discovered, immediately slow down, pull over, and check the situation. Small cracks can be handled with a car glass repair kit, which can be bought at supermarkets or online for just a few dozen yuan. The operation is simple—just apply the resin to fix it. However, if the crack is large, longer than the width of a hand, or near the edge, don't delay—go directly to a professional repair shop or dealership for a replacement. Don’t forget to check your car insurance; many comprehensive policies cover windshield replacement, saving you both hassle and money. To prevent similar issues while driving, maintain a safe distance from trucks to reduce risks. Not repairing it in time is not only dangerous but can also increase repair costs or affect the vehicle’s safety assessment. Don’t let small issues lead to big problems. Address it early for peace of mind.
