Tech Tips
GORMAN helpful hints

Ask the Doctor
by Walt Gorman

Q. I occasionally am unable to completely fill one leg of a star break no matter how long I work on it. All the other legs usually give me no trouble. This baffles me because I use the same technique on every repair.

All breaks are not alike, so you occasionally must use another technique. The ability to do the difficult repairs is what separates the professional repair technician from the "hackers."

First, be sure that the cylinder on your repair bridge is not screwed down too tightly on the glass, as this could be closing the legs of the break. It only has to be tight enough to prevent the resin from escaping. If this is not the problem, then the unfilled leg is probably not connected to the pit, or is too narrow at the point where it will not flow.

With the pump on pressure, first push down on the glass with your probe at the narrow point, holding it open until the resin runs into the unfilled tip. If this fails, remove your pump and press down on the glass with your probe, between the pit and the unfilled leg. This should crack the glass and allow the resin to flow.

Q. I am new in the windshield repair industry and one thing that has me confused is drilling. One person tells me that he drills every break and another tells me that he does not even have a drill in his kit. What is your take on this subject?

Bullseyes rarely need to be drilled, but 30 to 40 percent of stars and combinations need to be. Some technicians drill them all. Their rationale is that the drill hole is smaller than the pit, so it will not be noticeable and the flow of resin into the legs is easy and fast.
