So I've been spending the last hour sanding my valve covers like a madman so I can repaint them. I'm finished with the drivers side valve cover for the most part, but now I can see my hand prints all over the damn thing. I heard that there is a chemical that you can use to remove body oils and other impurities before priming but I have no clue what it's called. Can I use rubbing alchohol?
Thanks
