Is It Safe to Have Cracks on the Windshield?
2 Answers
Minor cracks can be repaired by yourself. If the cracks are severe, replacement is necessary. Relevant details are as follows: Impact of cracks: All automotive windshields are now made of laminated glass, which is safer but not as hard as tempered glass. However, the inherent properties of glass remain, meaning it can still be damaged or cracked upon impact by foreign objects. Cracks on the windshield not only look unsightly and obstruct vision but will also extend over time if left unattended, potentially affecting vehicle inspection. If the cracks are too long or severe, the only option is replacement, which not only costs more but also disrupts vehicle use and risks leaks of wind and water. To prevent further crack expansion, windshield repair technology has been developed. Windshield repair: Automotive glass repair is a technique that fills cracks with highly transparent and hard glass resin to conceal the damage and prevent crack propagation. The repair process involves using a vacuum pump to remove air from the crack, then utilizing pressure difference to fill the crack with glass resin, and finally curing the resin with a UV lamp.
Last time when my car's windshield had a crack, I was also worried about safety and felt nervous while driving. Actually, this situation is absolutely unsafe because it can expand over time, even affecting the entire glass strength. In case of bumps or hot weather, it might suddenly crack and block the view, leading to an accident. I experienced a small crack turning into a big one once, so I quickly drove to a repair shop for inspection. The technician said small cracks can be fixed with resin filling, but if it's too large or near the edge, the entire windshield needs to be replaced. To prevent worsening, I always park in a shaded area to avoid direct sunlight or strong vibrations. Remember, don't ignore it—deal with it promptly to avoid endangering yourself and others. The sooner you fix it, the sooner you can have peace of mind. Safety should always come first.
