The Question: I'm looking for a new pad to use with OPT Hyperpolish, what would you suggest? Details: Machine: Older Porter Cable DA (bought about 2007 but don't remember the number on it) Car #1: 2007 Acura MDX in nimbus gray with mild swirls Car #2: 2010 Lexus IS in Ultrasonic blue mica that still has moderate dealer installed swirls. Follow on question: noticed that Lake country has the 1-pad system but in reading I'm not sure that it would work for DA, only seems to be rotary. Am I correct and if not does anybody have experience with it? Thanks in advance, Tony
