It'* been a while, but I used to paint houses about 10 years ago. Sash is around a window. Trim is everything else. As far as brushes, I don't remember brand names but you want natural fibers, stay away from nylon and stuff, and get one that is comfortable. 2 or 3 if you can afford 'em, allow them to rest occasionally. Always clean them immediately, right now, as soon as friggin possible!! And store them hanging or bristles up, or they will lose shape.
