pics updated with what I used. I just kept the buffing sponge moist with alot of compound and then finished it with the polishing head. You can get the Novus at any plastic dealer. I just wish I would have got the deep scratch remover as well for a couple of scratches.
I would have never thought of using that stuff for a tank....I bought it to get the scratches out of my headlights, all 3 novus steps can be purchased at jcwhitney lol...looks great
