My old next-door neighbor painted his house when my car was parked on the street and some paint went airborne and landed on my car. Its not noticeable on the paint but its there and I'm going to clay my car next week and I'm hoping this will pick it up. The paint is real noticeable on my windows. Will clay work for removing the paint on the windows too? I'm guessing if it removes the overspray from the body it will work on the windows too? Also, my windows have real fine scratches from going up and down. Anyone have advice to reduce or eliminate these? Maybe a glass polish or a sealant? I have no idea. I feel like scratched windows really take away from the show of a spotless car.
