Can you feel any bumps or roughness? Clay it! If not, skip it. The sandwich bag test is important because our hands are too soft to actually feel the contaminates in the paint.

The main goal of the clay is to remove dirt and surface contaminants before you polish and wax.

Hope this helps

Nice! I do the samething but with the plastic wrapping on the outside of a pack of cigarettes. Works the same! Have you ever tried fallout remover?
