All, Got this, FREE, from railroad club member Thursday night. No longer needs, layout is now totally dismantled. Moving to assisted living. Comprised of what you see: Small tank, still holding compressed Nitrogen! 10' Hose and Badger 150 airbrush. Are there noticeable benefits of using Nitrogen for painting? Could I hook up a small compressor I have, to this set up, after purging all current gas, from tank? Has 2 regulators. I've got another regulator on compressor, as well as moisture trap. Just gotta find some sort of spray booth now! And maybe I can attempt to start airbrushing!
