I have an industrial rebreather (like pest control people use). My painting room is around 7ft x 12ft. It -IS- enclosed and I cannot open a window. Spray booths are just insanely expensive or really small. I was hoping I could get away with using my industrial rebreather. I'll be using acrylics with my airbrush except for occasionally when I prime or varnish with spray cans.
Thanks for the help.
