Rust

Cast Iron...nothing rusts faster than cast iron.

If you cook with cast iron and get the slightest bit of water? BOOM, rust.

Not if seasoned right! Love my cast iron pot. Very very well seasoned now.

Wonder if we can heat rotors in bacon grease and season them that well..... Rofl

You need to stop that right now.

I have to go to the gym now and you brought up bacon.

How dare you.

I know the surface rust is completely normal, but perhaps it's more noticeable or maybe even more prevalent because the wheels are so open to show off those beautiful Brembos? more openeings mean more water gets through the wheel? just a thought, the OP said they didn't see it on other cars in the lot...

EDIT: +1 for bacon..

I notice the same thing when I don't wipe them down after a wash.

I was wondering if it had to do with the rotors being new and having fewer hot/cold cycles. Someone at work suggested it could actually be metallic brake dust and not actually the rotor. Though I doubt it would be that uniform if it was brake dust.

It's oxidation on the rotors. It's completely normal. 100%, no equivocation, no hesitation, perfectly fine. It's only a few atoms thick, actually, if I remember my chemistry correctly.

You can get Zinc coated/plated rotors and that prevents the surface rust from happening.


LOL @ the bacon comments. I love me some bacon cooked in my cast iron skillet.
