I use PPE (gloves, mask, and glasses) when I'm spraying garden chemicals, even when I'm handling potting soil, the chemicals in that stuff is enough to make me careful. But I don't tend to when I'm detailing, but I don't polish much, maybe once or twice a year, and it's never that aggressive, so almost no dust. I occasionally wear gloves if I'm doing the trim, mainly when I was using Mother's CMX which says it has ceramics in it, I remember washing my hands after and the water beading on my hands, I basically ceramic coated my hands. If I'm wearing glasses it's more for seeing details than protecting my eyes, I know, I should be more careful. I've actually had a face full of wheel cleaner when the wind gusted as I sprayed a wheel, I immediately went and sprayed my face with the hose, luckily no harm done.
