When it reaches a certain length, only choice is to replace glass. It will cost several thousand yuan to replace windshield. Moreover, sooner glass is repaired after breaking, better effect, otherwise after a long time foreign objects will get in, which will affect final effect of glass repair.
The principle of glass repair is to use resin glue, which has high transparency and no glue residue. The glue is injected from damaged part of glass, and after curing, glue is all right. First, use triangular tray bracket to fix position, then clean hole punched out by stone, then fix glue injector and inject glue, and then use vacuum pump to pump out air inside, so that glue can penetrate cracks better, wait another four to five minutes, heat inside of glass with a lighter, speed up flow rate of glue, and make it easier to penetrate glass cracks, and then use pump that evacuate to squeeze it. Press and then penetrate innermost part with more force. In short, when degree of vacuum and penetration reaches limit, glass repair will be perfect, exactly same as original car glass.
