Don Stauffer:
I'd like to use pure turpentine- then I'd know pretty much what I was getting, but fifteen bucks !! So I'll just use the 100% mineral spirits paint thinner.
Why would you prefer turpentine? The smell would turn me off. I ended up with a can of it when my father-in -law passed away, but I don't think I'd want to put it in my airbrush. I clean up with lacquer thinner. It cost me $15 for a gallon, but that will last a long time. It stinks too, but I wear an organic vapors mask and it dissipates pretty fast.
