I did an Airbrush painting in Art 4 for about 15 years. I have stopped
because I don't have the room and I don't have the commitment from the students to
work that long on something. Oh the slides I can show but at such a cost.
Time is the issue here for me. I t take a lot of time to do the airbrush things
we were doing and They don't have it in them any more.
I used and still do the Passche h-3 series. This is a single action that can
be adjusted in mid stream but just not the flow. They are bullet proof and
will last a good long time. Easy to clean not much clogging (unless not
cleaned) and they have removable and replaceable parts. The adjustment parts were
$10-12 just recently and you can use the core forever.
I have friends who are professional illustrators who use this airbrush and do
so because of it's ease of use, clean up, cost and because it works. Check
it out and see for your self.
