Can a 15cm crack in the windshield be repaired?

[CharlesFitz]

A 15-centimeter crack in the windshield is too long to be safely repaired. It is recommended to replace the windshield with a new one at a 4S shop or auto repair shop. Here is more related information: Situations where the windshield can be repaired: 1. If there is a crack or scratch on the windshield, it depends on the depth, location, and size of the crack. In many cases, repair is possible if the length and area are not too large, and it can be fixed at a relatively low cost. 2. Most vehicle windshields are designed with a laminated structure, where the inner layer is tempered glass and the outer layer is laminated glass. If the crack only appears on the outer laminated glass, it can be repaired. Side and rear windows, however, are made of tempered glass, which shatters entirely upon impact and is difficult to repair. Spiderweb-like chips within 2-3 cm in size can be repaired, but chips larger than a coin are hard to fix. Linear cracks can also be repaired if the inner tempered glass is intact and the crack is around 15 cm long. The sooner the crack is repaired, the better, to prevent further expansion or contamination by debris, which could affect the repair results.
