I bought one several weeks ago and love it. I will never wax again without one. The pad choices are similar to what is available for a PC. I used the orange pad that came with the Wolfgang Polishin Pal and Poorboys Pro Polish and the results were very good. It saves your fingers from the cramping that
you get using a applicator. I used the grey finishing pads to apply my Poorboys Ex and then Nattys Blue. I have not bought a PC yet and will be very soon. You really need one to correct swirls and polish. I will not however use the PC for the LSP as I have read that Steve (PB's) suggest the LSP be done by hand as the PC might remove some of the LSP layer from previous
sealant or wax. That is just an opinion and we all have our own. But you can't go wrong using one of the Polishing Pals. They are just a good tool for detailing.
