Can Glass Cracks Be Repaired?
2 Answers
This situation depends on how severe the glass crack is. Some cracks can be repaired, but the prerequisite is that only the outermost layer of glass has cracks. Generally, repairable crack types include star-shaped cracks and linear cracks. If the crack is too large, it is recommended to replace the glass. 1. Glass Repair: After the glass is damaged by being hit by a hard object, the method of repairing the glass by filling resin into the dents and cracks is similar to the current form of resin dental fillings. Glass repair has the advantages of short operation time and low cost, but its limitation is also very obvious—it can only repair small cracks or minor damage on the windshield. 2. Precautions: If cracks appear on the windshield, they should be repaired as soon as possible. Otherwise, with temperature changes, heating and cooling can cause the glass to deform, and continued driving will further erode the damaged area due to wind resistance, continuously applying pressure. The damaged area may expand, and if the optimal repair area is missed, the repair effect may be significantly reduced.
As an ordinary driver with decades of experience, I can confidently say that glass cracks can be repaired, but it depends on the situation. Common small cracks, like coin-sized star cracks or small gaps on the windshield, can usually be fixed with resin injection. This kind of repair is quite affordable, costing only a couple hundred yuan, and a professional shop can get it done in just a few dozen minutes. However, if the crack is longer than two or three centimeters or is already spreading, then the entire glass needs to be replaced. Otherwise, exposure to wind and sunlight while driving will accelerate the crack's growth, affecting visibility and safety. I've encountered this situation several times and recommend addressing the issue as soon as it's noticed to prevent it from worsening. Once repaired, it maintains the original glass strength, unlike a replacement, which can be costly. In short, fixing it early saves trouble and helps avoid accidents.
