Hi -
Since I don't have a fresh-air mask, and filters don't do it, I'm modifying the mask to breath through a reaaalllly long flexible hose while I lie underneath and spray the primer, then the undercoating. Not sure how well I'll be able to see when I get to spraying the undrdcoating. I think I'll carry a thinner soaked rag in my back pocked to I can wipe off the sheild.....

Here's a few tips...in order for a fresh air system to work, it has to be POSITIVE pressure - not just you breathing through a straw. You have to force air out of where you breath or the nasty stuff still gets in. This is a safety issue and should be done very carefully. Get a vacuum cleaner motor and use the reverse flow (not suction obviously), then get an AC speed control and a filter in place of the bag. This is essentially what my fresh air system is - pretty simple.
When spraying undercoating, the only way it would get on you is if you turned the gun around and pointed it at your face...don't do that. It comes out in a thick mess - not much overspray at all.
