>>8765348I wear a respirator when I spray because of the blowback that you can get when you spray certain parts at certain angles. It only takes a second to get paint in your face and no booth will prevent that.
I don't need respirator to save me from fumes slowly escaping the booth, because my extractor fan is powerful enough and that doesn't happen. When I clean my airbrush and spray into the pot I don't wear any respirator and I don't smell the thinner.
