Can a Cracked Windshield Be Repaired?
2 Answers
If the damage area is not large, it can be repaired. However, if the damage is too extensive and poses a safety risk, replacement is necessary. Below are some related tips for windshield maintenance: 1. Regular cleaning with glass cleaner: Use specialized glass cleaner for cleaning. Glass cleaner not only keeps the windshield clean but also increases lubrication to prevent damage from wiper blades. 2. Proper application of car window film: The light transmittance of windshield film should be greater than 70% to ensure driving safety. Avoid using dark tinted heat-resistant films. Additionally, choose films with high UV protection indexes to protect dashboard components from premature aging due to prolonged exposure.
Last time when my car windshield got hit by a flying stone, I consulted a friend at the repair shop. They said cracks smaller than a coin can usually be repaired, but three conditions must be met: the crack must not penetrate the outer glass layer, the crack ends must not have branches, and it must not be directly in front of the driver's position. Professional shops use vacuum equipment to inject resin into the crack, and after complete curing, the strength can be restored to 90%. However, they specifically warned me not to compromise in two situations: first, if the crack length exceeds that of a 50-yuan coin, and second, if the damage reaches the middle of the laminated layer. Repairing the glass only cost a little over 200 yuan, saving me more than a thousand compared to replacing the entire windshield.
