Never pour hot water on your automobile windshield chip repair. If you walk out and notice that your windshield is icy, you may consider pouring a large cup of hot water on the glass to melt the ice. This is actually a very bad idea. Large temperature changes can cause the glass to crack. It is best to turn on the car defroster and let the glass slowly warm up. The ice will melt away safely without damage to the glass.
Good question. Windshield crack repair equipment varies widely among companies. High quality resins, injections and air removal methods vary from company to company and can affect the finished repair. Quality injection units and high quality resins are as important as the technicians performing the crack repairs. The quality resins create stronger bonds and resist yellowing better than inexpensive resins. Quality injection equipment will remove more air and the injection capabilities provide a higher quality crack repair.
If your vehicle really needs a windshield repair, make sure to get high quality glass. Have it installed properly and choose a good adhesive because it is essential in windshield installation.
As a windshield installer for the past thirty five years, let me give you three good reasons not to repair your windshield. As windshield repair is a gimmick in my opinion.
A surface pit is a nick in the glass associated with normal wear and tear that does not penetrate to the plastic inner layer. This can be repaired if the damaged area has a diameter of not less than 1/8 inch.
To further strengthen the windshield, the auto glass is subjected to a tempering phase. The sheet is heated to a temperature of 1565 degrees Fahrenheit or 850 degrees Celsius. It is then subjected to blasts of cold air. A piece of PVB plastic is sandwiched between two pieces of auto glass. The sandwich is heated inside an autoclave. This bonds the components together tightly and removes any trapped air.
