Not all windshield chips and cracks can be repaired. Windshield cracks over quarter size, rock chips that penetrate all the glass layers, and large chips have already compromised the windshield’s structural integrity and cannot safely be repaired. Also, cracks and chips in the driver’s line of sight will require a windshield replacement as the finished windshield repair resin does not dry perfectly clear. Your windshield plays a vital safety role in the event of an accident. It keeps the passengers inside the vehicle during a rollover as well as providing a barrier to flying debris. However, once the integrity of the windshield has been compromised by a rock chip, stress crack, or other damage, the windshield’s ability to protect your friends and family is severely diminished.
