Well one of the reasons this came up is a guy pulled out in front of me and I laid it down. So some of the plastics are scratched a little. I'd only be saving 2/3 of them.
Never played with the stuff before, but that's a good idea. Will it stick to the scratch on the plastic where I laid it down, or will it peel off of that too?Since you want a matte color, why not plastidip? Then if you dont like the color you can rip it off and only wasted like $20...
