I do not treat my soft tops very well. In the summer they usually just lay in the garage or on my other zook. then there is all the NW wheeling I do. So the windows get very scratched up. Well I thought I would try one of those plastic polishes and see if it did anything. Whoa boy did it.
It is hard to see in this picture but the left side is polished on the outside only, while the right side is polished on both sides. I did it all by hand and am convinced that if you used a power buffer it would come out a ton better.
It also seems to work well on old oxidized plastic. Stuff like the bug sheild on my pooper duty.
Anyway I was just very impressed with this stuff.
