You got pads already? I got the 3M pads (green, blue and orange iirc) which were good. I use Gtechnics P1 also, which is a very, very good all purpose polish IMO. Used the cutting pad first, then, even though i didn't need really need to, refined it with the polishing/finishing pad. This was on hard paint, but apparently even on softer paints, P1 finishes well without leaving much in the way of buffer trails/hologramming, even before using a finishing pad.
EDIT: I just used the standard pad and it was very bouncy and uncontrollable at times. Apparently it is absolute crap, and a better backing plate would have stopped almost all of this.
