The reason that cracks often start on the edges of the automobile windshield chip repair is because the edges are the structurally weakest area. The frit is on the glass because it keeps the ultraviolet light from the sun away from the polyurethane seal that holds the windshield in the frame. Without the frit, the windshield would quickly start leaking or just pop out of the frame of the car.
If you have a leak it's very frustrating. But spending thousands of dollars on interior pieces or your electrical system will make you even more frustrated. You need to call your auto glass company and have it fixed immediately.
Driving the car immediately after a windshield repair is not something you can do. There is a time period that should be allowed to make sure that the window has settled and dried. The warmer weather allows for the adhesives to dry quickly. However, the colder weather increases the time that is needed before you resume driving. Taking the time to wait for the adhesives to be at full strength could mean the difference between life and death or an accident that leaves you maimed.
Use your defroster on high. Extremes in temperature are never a good thing for a cracked or damaged windshield. If you live in an area where you are required to use your defroster regularly, gently warm up the car over a period of time. It's also best to find a mobile windshield repair company that can do your repairs as soon as possible.
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.
