The truth is that nothing can remove the tiny pits "road rash" from your entire windshield. If I had a product that would do that, I'd be living in Monte Carlo typing this from (one of) my yachts. This usually just happens in time with all cars that are driven out on the freeways. Really can't be prevented and the cure is a new windshield. You'll find that 99% of all auto insurance companies will not replace your windshield for just road rash. It usually has to be broken and even then, if it's just a minor chip or "star", as we call it, they will attempt to talk you into having it "fixed" instead of having to pay to put a new windshield in. Do you see where I'm going with this? (HINT: BRICK)
No, I'm not telling you to take a brick to your windshield, but if by some chance there appeared a long crack in your windshield, then it would have to be replaced, wouldn't it? (HINT #2: CHECK YOUR GLASS DEDUCTIBLE FIRST) pete the ex glass guy......PS>>>and no, there is no "clear film" you can use on a street car to prevent chips and road rash even though they make this stuff for racers>>>forget it for your Viper.
