HAHA,
yea I have had the same experience with the powder igniting. Only took doing it once to realize this is some dangerous stuff.
As for using the heater I mentioned before, the powder is not being applied while the heater is on. I coat my larger parts than move them to a clean "powder free" area to be baked. There isn't any air born powder, only the powder that has been applied to the parts. I really see no different in using this type of heater than using a gas kitchen oven and have great results with using it. "Knock on wood" I have made the mistake of sticking my head over the top of the heater while in the middle of baking. BIG BIG mistake. It was so hot that I burnt off every piece of hair on my face. Including my nose hair.
