Stock rotors are made out of plain,non-coated steel. The reason the main surfaces don't rust is because the they get polished every time you step on the brakes. The rest of it, however, will look just like any other piece of steel left out in the elements, over time. Yes, it does get to be unsightly. The solution, as suggested above, is to remove the rotors, sand, wire-wheel, or sandblast off the rusty places, and coat those places with a rust-resistant coating. Alternatively, you could replace them with custom rotors that are coated, or made out of a non-rusting material (stainless, ceramic).

It's iron. Iron + water = rust. There's nothing you can do to keep it from rusting unless it's always kept in a climate controlled moisture free environment. It's going to rust no matter what you do. Painting or powder coating it will be worse because it will just come off and make it look crappier than the rust. The only way that I know of to keep it from rusting is to get some rotors where the hats are aluminum instead of iron. I have 2 piece rotors that have aluminum hats and they don't rust. But they are pretty expensive.

Cool, another rust on my rotors thread.
It's his second car, but apparently the first one he's paid much attention too.
