Could the "rust" be coming from the rotor hub itself and working it's way out.
If water gets in there, I'm sure it does, then it will forum a rust soup.
That might eat at the finish of the wheel.
The wheel and cap I don't think will have "Iron" rust.
Any place water can collect, needs a drain to get rid of it quick and allow it to dry.
I wonder if putting a fine notches in the cap might be worth it.
