Well, yes, the friction removes the coating from the stopping surfaces, but the rest of the rotor remains protected, including the inside fins, which really take a beating in salty areas. The braking surfaces don't need corrosion protection for anything other than storage, since the pads continually sand away any rust. It's the rest of the rotor that benefits from the coating.

The ATE PremiumOne coating is different than any I've seen, it resembles silver radiator paint.

Front set on my '88 560SEL from Advanced Brake Technology. Good fit and a precision made product. Oh, and they stop well from triple digits and again!
