I'd like to try HOK urethane-based paints, but I'm concerned about respiratory safety. How do you guys deal with this? As I understand it, this stuff is basically airborne super glue and can cause some serious health issues. I use a respirator with two screw-on paper filters on the front, and I have a large window fan blowing outside right next to the bench where I set up the airbrush. I'm thinking I need a spray booth with built-in fans or something like that, but I wanted to hear your experiences with this type of paint.
