Had a rag that i used to clean a spot and put the rag down and it scarred the lexan window is there any fix to cleaning it up has small raised spots on it?????

Sorry to say that's the worst thing that can happen to polycarbonate. It is much softer than Plexiglas and the surface will dissolve faster, but it is much safer to use and will not crack like Plex, but both polycarbonate or Plex. will suffer the same from liquids like carb and brake cleaner. Where is the damaged area? windshield, side or back? Bob

back corner of the rear window.

Meant to tell you and maybe you already assume that it won't polish out and you are right. I have Lexan Margard II glass replacements and have a small flawed area on windshield in bottom corner, I covered it with a small "test n tune" decal (food for thought) Margard is now the go to product for glass replacements on race cars, but that also needs to stay away from brake cleaner lol.
