no classical muzak here, but i blast the non wear surfaces of the rotors with steel shot, then paint with whatever hi temp stuff i have on hand. that really keeps the rust down, but there are a few spots that still get a little bit. i also smear a small bit of hi temp anti-seize where the hub passes through the rotor, as well as cleaning the hub face mounting surface very well, and applying a touch there for good measure. your results may vary.
