I prefer to use pressure-sensitive adhesive (PSA) backed disks on my random-orbit sanders, but peeling off the old, stuck-on paper can be a real chore. Here’s the easy way to do it: warm it briefly with a heat gun, and the paper will peel right off without leaving residue on the pad. Sure beats using solvents or a scraper to get the paper off!
