Windshield Repair Forum

I have never had this request before. This guy called and said he had a chip and small crack on the inside of his windshield. Said his windows were down and he was using a weed eater when a rock flew inside. After much discussion, I declined to attempt the repair. Can any of you repair an inside chip?

My equipment can do it but I will not do it in the direct 9"x11" square in front of the driver.(what I referr as the "liability" square) also it is hard to set up a repair if it is too far down the glass(dashboard interferance)
