I just got my PC from Coastal Tool with the bonus 6" hook and loop contour pad. I have never used or owned one of these but I am very serious about car care and want toget tothe next level. The PC came with a big white polisher, I took that off and screwed on the 6" contour pad. What is the next step? Do the foam pads attach to this? Do I need anything ekse besides the foam pads at this point?? Also will I ever use the big white pad it came with? I switched the counter weight to the 6" one they provided before I attached the 6" pad. Will I need the 5" one they gave me? If so for what. I would appreciate some information on this subject since I am new at this. Thanks BOBBY:badabum
