Can a Cracked Windshield from a Stone Impact Be Repaired?
2 Answers
Glass cracked by a stone impact can be repaired, provided the crack is smaller than the area of a one-yuan coin. If the crack exceeds the size of a one-yuan coin, replacement is necessary. Below are the hazards associated with windshield cracks: Crack Propagation: Once the glass is cracked, air can enter the interlayer of the glass. Over time, this may cause the glass interlayer to separate. Additionally, the faster the vehicle travels, the greater the pressure the windshield endures, leading to further expansion of the crack. Impaired Visibility: An expanding windshield crack not only obstructs the driver's line of sight but also poses potential safety risks. If the front windshield is cracked, prompt repair or replacement is essential.
A stone chip in the windshield can often be repaired, depending on the specific situation. Small cracks, like bullseye or star-shaped ones under 1-2 cm in diameter and located away from the driver's line of sight or the edges of the glass, can usually be fixed by professionals using resin injection. They'll clean the crack, remove air, and inject a special resin that hardens to reinforce the glass—effective and cost-saving, avoiding the expense of a full replacement that could cost hundreds or even thousands. However, larger or deeper damage, like long cracks or penetrations, might not be repairable. I recommend getting it assessed ASAP; rain or temperature changes can worsen the crack. Post-repair, the glass regains strength, ensuring safety and peace of mind.
