I have been reading on this forum about how to restore my first vintage kit. The kit is an old sonor, and the wrap is scratched up pretty bad. I did some work with auto wax, and it made it shiny, but scratches are still very visible. I read that the Novus works well, so today I went out and bought 2 and 3 versions for light and heavy scratches. The #3 said not to use on covered plastics. Does anyone have experience with #3? There isn't much room to test it out, i guess under a lug, but before I do, I'd like some advice or feedback.

Thanks!
