Im still pretty new when it comes to buffing and polishing and only have the 3 pads that came with with HD polisher kit, I've done some pretty decent correction work with the pads but im still in the dark when it comes to maintaining the pads. I plan on buying more pads from LC because there factory is 10 minutes away from my house, what kind and how much of each pads should I buy? Im planing to work with the HD line and maybe megs down the road.
