very interesting comment on the respirator issue. I decided no to use a 2 part paint for another reason, but all the better now. With the brightside brand paint do think a positive pressure mask is still required, or just one of the organic (carbon) 3M units. If you think that a positive one is required then do you know if a unit that can be operated from a standard air compressor (with pressure regulator of course).
