Count me as one more who just took the PC plunge. After a LOT of reading here, I ordered the bonus kit from Coastal. A couple of questions that I didnt' see in the old threads. 1)How often do you polish. Can you polish too much? 2)Pads, Pads, and more Pads. Is there really a difference between all of these pads? I can certainly see how a real aggressive/wool pad would be extreme, but is there really that big a difference between the other "middle of the road" pads i.e. polishing/finishing etc. Seems that it's just a way for the manufacturers to sell more pads?
