Will the repaired windshield crack again?

[StAndrew]

Generally, a repaired windshield crack will not crack again, as the glass repair process involves extracting the air from the crack to create a vacuum, then injecting a glass repair agent to fill the gap. As long as the crack is not too severe, the structural integrity of the glass will remain largely unaffected. The lifespan of a repaired windshield is also quite long, typically lasting at least 5 years or more. Therefore, when your car's windshield has bullseye damage, chips, cracks, or long fractures, there's no need to rush to replace the glass—repair can be just as effective. To ensure the quality of the repaired glass, it's important to seek out professional repair shops or authorized 4S stores. Additionally, avoid driving quickly over rough roads and try not to park under trees during windy or rainy weather.
