Windshield chip repair is more than just filling chips & cracks. Any time you can repair your windshield and maintain the factory windshield bond by not replacing it is extremely encouraged. In the uneventful situation of air bag deployment the factory windshields bond is more superior to any aftermarket adhesive. This is critical to keeping the air bag deployment inside the vehicle during an accident. In addition to safety, with a lot of newer vehicles today they have what we call Advance Driver Assist System or (ADAS). The ADAS controls features like lane departure warnings, brake assist and automatic headlights. Every vehicle with ADAS needs to have it recalibrated when you replace a windshield. This increases the price of windshield replacement signifigantly and could potentially cost you thousands.
