Tiny nit, Jim, but it's the other way around. Rust is basically ferrous oxide, though hydrated and with other compounds also, depending on the environment and temperature of the rusting.
Ferrous oxide, like most natural oxides, is stable as is (note I didn't say "rust"). But PAINT can weather and deteriorate, even if its pigment is stable.
