Yea, that's basically what I'm wondering Skip.
I'm hoping to seen be in a situation that I need to take one before long and want to make sure that if I work with some paints, model cement, or other adhesives while working on plastic models or R/C stuff, I won't have any issues caused by the proper use of the stuff. I bought a 3M respirator a while back and try to use that while spray painting stuff, kinda wondering if I should use that if I work on anything else if I do get that opportunity too.
