What's the best way to treat rust that has devloped near the rocker panels, and wheel weels (after some paint chips that I didn't notice). Is it a matter of cleaning, priming and using the same colour paint to cover, or is it more complicated (or easier) than that? Until then, what's the best way to protect the area until the "touch-up" paint job? I've heard of motor oil, WD40, etc. after washing it, just to "coat and protect" it.
