If working by PC, I would personally recommend using the Power Gloss on a 4" yellow cutting pad as the 4" pad can generate a little more heat by PC and breaks the aggressive compund down that little bit more effecticely to leave a little less micromarring. Though it will still leave some. Be aware that PG will also kill off 4" pads quite quickly though.
I recently tried out the
Menzerna foam pads, and the white compiunding pad I have got the best performance out of PG by PC with... Its a very coarse pad and leaves micromarring (needs to be followed with lighter abrasive but thats par for the course for aggressive compounding) but is very effective at removing defects coupled to the Power Gloss product.
