Yeah, the Badger works great, but paint thinner does jack squat to the moly resin. You have to use the Methyl Ethl Keytone to clean up the airbrush, its the only stuff that will do it.
I'm using a gigantic Sanborn air compressor that also powers our bead blasting cabinet. Unregulated it runs as 120 psi, so I regulate that bad boy down to about 60 before running the airbrush. Anything between 60 and about 35 psi seems to work just fine. If the pressure builds up too much I run the airbrush with air only for a few seconds to bleed it down, then pull back on the lever to start the moly flowing. That's why a dual-action airbrush is absolutely necessary for this kind of work IMHO.
P.S. Norrell's HK Socom Black is what I would recommend to go with the plum furniture. Did you see the pics of the G3 I did in that?
