Fumes from enamels, brush painting?

paint in your garage or outside.

Fume is always an issue no matter if you spray or brush, just opening the jar will release the fumes. And if you breath it, it'll get stuck in your system essentially forever and build up as time goes on.

I wouldn't touch any paint unless I have a respirator and there is very good ventilation.

what I mean by "no outside air source", is no fresh air coming in from the outside.

Gip,

Thank you again sir. I didn't think brush painting with a fan would be a problem, but had to check. I'm still leery about airbrushing as I have no outside air source, and my hobby room is small and the fumes can concentrate easily So the way it has shaped up, is that warm weather months are my time to build models, and cold months are for miniatures.

Hi, DJ.
Have fun brushing! There should be no cause for concern. Problems begin to arise when solvents are rapidly vaporized (as in spray painting), and the vapor generation rate is faster than the available fresh air and/or air movement can handle and effectively dilute the vapors to what is considered a safe level.

You know, with fans running, doors open, and wearing the appropriate respirator, there should be no reason why you probably couldn't do a little airbrushing. You might want to try it, and see how it goes.
If you have specific questions, let me know.
