I use a bit of Vaseline (petroleum jelly) on the moving parts. Works for keeping the trigger and movement smooth without traveling through the brush. If I have a sticky air valve, I'll drop some 3 and 1 oil into it, but then I'm spraying out oil residue for the next half hour, so I don't due this very often. I also keep my airbrushes segregated (some used for oil based paints, some for water based paints), as I've found airbrushes that have been used for spraying oil based paints will be awful at at spraying water based paints. I have always kept my needles dry and clean. This thing I'm reading about with the balm is new to me, but if it really helps with tip drying I'm all for trying it out.
