For a street vehicle, the rotors don't typically get to the same temps as a "sporting" vehicle so the transformation to cementite will be slower. If you used regular silicone carbide paper in the belt sander, don't be surprised if you start to get some pulsing in those brakes. The rotor actually doesn't wear as much where the cementite forms and so as the rest of the rotor wears, you will have thick and thin spots creating the pulse.
