Frequently Asked Questions
What is Windshield Resealing?
Windshield resealing, also known as windshield re-glazing, is the process of repairing or replacing the rubber seal around a car’s windshield to prevent water from leaking in and to maintain the structural integrity of the vehicle. The seal is usually made of a rubber or vinyl compound that surrounds the windshield and is bonded to the vehicle’s frame. Over time, the seal can deteriorate, causing water to seep into the vehicle and potentially leading to costly repairs.
How Does Windshield Resealing Work?
Windshield resealing involves removing the old sealant, cleaning the area, and then applying a new sealant to the windshield. This process can be done using a variety of methods, including applying a sealant to the windshield and then using a tool to spread it evenly, or using a specialized kit that includes a pre-mixed sealant and a applicator. The new sealant is then allowed to cure before the windshield is reinstalled.
Why Should I Reseal My Windshield?
Resealing your windshield can provide several benefits, including preventing water from leaking into the vehicle, reducing the risk of rust and corrosion, and maintaining the structural integrity of the vehicle. It can also help to improve the overall appearance of the vehicle and prevent the growth of mold and mildew.
