Any of these stone chips can be repaired. Beyond looking for these types of common chips, it is important to take into consideration the size of the damage. If the damage cannot be covered by a half dollar, the chip is too large to be repaired. Another important piece of information to consider is the acute area. The acute area is the area of the automobile windshield chip repair directly in the drivers line of vision. It is the same size as a piece of paper being held horizontally in front of the driver. In this area, the National Glass Association does not recommend a repair being done unless it is no greater than .95 of an inch. An easier way to imagine this is that a quarter should be able to cover the entire area of damage in the acute area.
I have seen this procedure first hand and walked away shaking my head wondering why anyone would want to do this to their windshield.

Carefully read and understand the instruction manual that comes with your newly purchased windshield repair kit before performing the repair. Now, here's how to fix the cracks on your windshield. First, use an auto glass cleaner to remove dirt from the crack and the area around it. Then dry the crack using a clean rag or towel. Use a safety pin to take out any remaining debris on the crack. Next place the suction cup onto the windshield using the adhesive included in the kit. Then mount the injector on the suction cup. Next, inject the resin; this will remove the air between the windshield and the suction cup.
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.
