The little foam brush works for cracks and crevices. As long as the paint gets in there you should be OK, since you dont need to worry about sanding and polishing there. When you're doing that, you can move the paint around with the foam brush even to where it looks slightly uneven (it's tough to get it to look even unless there is a thick glob of paint), in my experience it levels/evens out on its own.

and a quick rub with mineral spirits works wonders to get the paint off. I've been doing that, and I'm not dead yet.
