There's something about those disposable latex or other gloves I dislike. You don't get as good as a feel with the razor or scales when sanding or working on them. It's different for mechanics. They are usually tightening or loosening stuff with a wrench or moving parts in or out. With restoration you are actually working on one piece and the precise feedback is very important. With gloves you lose that feedback. YMMV off course. Same with condoms ;)
