Yeah these new rotors get the coating usually on the whole rotor then the first few scrapes of the pad wears contact surface coating off but it shouldn't really rust as much either right?

I kinda wish the previous owner didnt do new rotors and pads before I bought the car, I'd like to go with the "reduced rust" coated slotted rotors and some nice Hawk Pads, would get my rotors from here adam's rotors | custom brake rotors, made-to-order
