I sandblasted my steel rims, then painted with silver engine paint, then
baked. The paint is not very durable, and (probably because I didn't use
primer) the wheels are rusting. >>
Ulix--
Primer will enhance rust rather than inhibit it--unless it is the new epoxy or
urethane primer. The red oxide and the gray stuff are like sponges-they will
absorb and hold water thereby promoting rust. Methinks the fact that you have
rust speaks not well for the paint you used and/or the coverage you got.
Paint is non permeable--wont allow water in if the seal is not broken, and
there should be no rust--unless something happened to the paint seal.
My pocket change!
