Were you detailing outdoors or indoors? Were the pads brand new? I know sometimes when using older pads or discs of other kinds that lose their abrasive quality, and can form pigtails. Did you make sure to keep your hands clean, so often I transfer dirt from picking up the polisher or moving the cord, so im super careful and wash my hands often. Dont lose confidence, anything you screw up can always be fixed...for a price
