So you’re lazy — the truck only gets a few coats of wax a year. It’s work doing it by hand, and you’re too cheap to buy a dedicated buffer. Instead of investing in a new tool, save some dough and grab Porter-Cable’s lambswool polishing pad. It comes with a hook-and-loop backer that fits the orbital sander you already own.
The polishing pad attaches to most 5″ orbital sanders that use hook-and-loop paper. To accommodate people with larger 6″ sanders, Porter-Cable also makes a larger 6″ version. Either pad’s fine lambswool will buff and polish surfaces to a high gloss with no scratching.
