Question:

Is there a difference in windshield repair resins?

Answer:

There absolutely is a difference in windshield repair resins. We have tested resins that, when cured, do not even stick to the glass. In fact, we believe this is one of the main reasons some companies do not sell pit resin. A poor quality resin will shrink up quickly and the “pit” will fall out over a period of time if the bonding strength is substandard. A high-quality resin will actually etch the glass just enough to create the optimum bonding surface, will not shrink, discolor or fall out of the pit area. The etching is microscopic and cannot be seen by the naked eye, so you need not be concerned about any cosmetic damage to the glass.
