windshield scratches
Well i can give a little inside to cerium oxide, Me and my family owns a optical lab, we make glass and plastic lenses for Dr's around the country. We use cerium to make glass lenses clear and smooth after we do the ruff cut on the blanks. It is a lot like polishing compound used on paint. You can take some of it and apply it on with a brush over the scratch, and take a little buffing pad on a drill or air buffer and keep working on it, " the pad that would work best is one that is like a felt pad, or harder foam pad. You can do wool but it will not work as fast or good. Maybe you can look in the phone book by you to see if anyone makes glass lenses. Its getting to be a lost art, everyone seems to be just doing plastic and not glass anymore. If you find someone bring a little jar for them to put it in. Hope that helps out a little. If anymore questions just ask. Rocky
