Ok, tinted my rear tail lights, decided I didn't like them and now I want to take the tint off. Someone told me that regular paint thinner would do the trick. I put it on only to realize that to take it off it would require scraping with a metal tool... If I do that I'm going to scratch my lenses to all hell. Any idea how to get rid of the tint? and to get rid of the paint thinner which is on one of them?
