I'll have three people brush painting 600 sq ft at a time on each pass. I suppose I could mount a fan in the window with air flow directed out, sealed up real good to keep any dust from floating back in, but I really thought I'd get the best finish if I kept dead air.

Just hire some illegals... they don't need no stinking respirator...

I would keep no air flow as well. With three people and 600 sq ft you won't be in there for too long on each coat. Good organic vapor respirators will be fine.
Biggest problem I think you are going to have is the extended beer break between coats, 5 hrs is a lotta drinkin' time

maybe CLK man would like to help
