And if you do buy the Iwata Lube, which I do, get the small little tube. Unless you use and clean 4 airbrushes a day the bottle will go bad long before you run out. I only do a tear down cleaning after a build is complete. I'll do "quickies" during a build. Lacquer thinner blown through at 65 psi, pull the needle and wipe down. If I'm done for the day, a quick squirt of WD40, blow it through at 65 psi. Before I start spraying again, lacquer thinner at 65 psi and rock n' roll. It's a process but with the money I have invested in airbrushes it's well worth it.
