I have 2 cars that have scratches caused by using windshield wipers called "winter" blades. They have a boots around the wiper bodies to prevent ice build-up. The boots are capped at each end by plastic caps. The plastic caps have scratched both cars on the passenger side where the outside end of the wipers sweep. The cars are driven by my wife and daughter and unfortunately, they failed to notice the problem until too late. I'm steaming mad at the manufacturer of these blades and plan to complain to them, but I'm sure it will do no good. I've tried every kind of rubbing compound, polish, etc etc in my arsenal with no apparent results. My question is, can a pro glass shop do anything to polish these out any? Any other suggestions would also be appreciated! Thanks..
