I prefer to go a step up on rotors, looking for coated ones, and scuffing the coating will expose the iron, promoting rust which I imagine will fuse to the buffed hub as well.

If you have a wire brush you can put in a drill that works well, if not 220 grit sandpaper works fine, just takes longer. If you don't do this you can get a vibration when applying the brakes similar to a warped rotor. (yes I know that's an inaccurate term but everybody knows it)
