To test this comfortable Pad Holder we polished and waxed an entire GMC Denali using our 3" foam polish and wax pads. While this isn't the most practical way to detail a large vehicle, we must say we didn't suffer hand cramps or get sore at all. Made from firm, dense foam; the back features hook-and-loop for use with any of Griot's 3" or 4" pads.
