I am thinking about getting a PC. I mainly want it for light polishing/swirl removal and some waxing. I was just wanting to know what "extras" I should buy? Other than what it comes with, what other pads, counterweights, and accessories should I buy? Keep in mind I am only using it for personal hobby and won't be dealing with too many abused/swirled finishes, so I don't need every pad for every situation, but I do want to know from those of you who are experienced what I should get as a basic start-up. Thanks!
