I read through this text and just have to clarify one thing. A windshield chip repair cannot be done properly without attempting to vaccum the spot. Drilling is usually, but not always, necessary. As far as using a lighter, that wasn't the bad part of the repair. All that heating does is expand the glass causing the crack to temporarily receed and allows the vaccum that is on it to remove as much air as possible. Then pressure needs to be applied as the glass cools and allows for the "resin, " not "lamiate, " to be injected into the chip. The resin itself is "solar reactive" which is why a longwave ultraviolet light is used but which is not needed in the sun. However, if the resin in this cheep kit was placed on the chip in the sun with no cover it would have no time to get into the chip thus being completely ineffective. It wouldn't even stop it from running. Whoever did this repair was obviously inexperience. I really do feel for you and am glad to hear that you didn't just sit on your [censor]. You actually got ahold of the BAR(Bureau of Automotive Repair). I really gives those of us doing things right a bad name creating a fear of replacement and reapair. Any questions-weazle777@hotmail.com
