Rotor rust.. prevention?

Ok normally when I want something to stay rust free on the undercarriage, I wax it, paint it, or I wipe a bit of penetrating oil from a rag onto the part.. This is not gonna happen with a brake rotor..

Painting it with a caliper paint is one option, but I fear any overspray that interferes with the pads will lead to fail. These are new stock type rotors and they shine so sexy..I would just hate to see them rust up.

Any ideas?

I guess if you don't drive it. They won't rust. Just don't have a clue I don't think there is anything you can use on rotors.

Exactly the opposite is true.

You must drive it constantly to avoid rust. The pad contact will keep the rotors rust-free.

Now, if we could do something to change the humidity level where we live...

I painted the entire rotor with cast blast and shortly after removed the paint from the pad contact area with laquer thinner. So far no rust. mike...

Don't paint them like this though.

Mask off the contact surface on both sides. You can then paint the hats and the vents. If you miss on the masking, you can use thinner to remove the paint from the contact surface. I've used black high temp bbq grille paint on my old C5 and on my 82. My 06 has some grey coloured coating from the factory and only rusts on the contact areas after I wash it.

Its in the garage mostly but flash -rust is almost immediate after a good wash.

After all the effort to make the suspension components appear sexy, it's a shame to have a rusty old thing staring you in the face when you look under there. Thanks for the advice.

i painted mine and didn't mask, nor spray directly on the contact surface, so there was just overspray,
and 1 trip around the block took off the overspray and gave it a nice paint edge too.
