I have an 8 year old MW that works fine. It has a rotating tray and there is a plastic thing under that tray with 3 small wheels. Where those wheels contact the bottom of the MW, the paint has worn away exposing bare metal, which from spills and such, has rusted. Before the rust gets real bad, I'd like to paint that part of the bottom. Do I need a special paint, or can I just use any common white spray paint? I'm not concerned about a perfect match to the color, just protecting the metal. OR, do I need some special paint?
Yea, I know not to cook in it for a day or more after painting, so it dries well.
