I've read several of the airbrush and paint threads, but I'm still having a heck of a time with mine. I have an old Paasche VL (at least 20 years old) and I'm using Lifetone lacquer based paints. I'm using a standard large garage compressor (my husbands, and I recently drained all the water from it) with a separate regular with a water filter between the compressor hose and the airbrush hose. No matter how much I mess with the thing, it's starts to gum up and spit. Just when I get a great tiny or thin paint going, then nothing and splat! So frustrating. I've tried adding retarder with no results. What am I doing wrong? I'ts gotta be operator error, because all the treads I've read people seem to be using the same products with excellent results. Even cleaning the airbrush, I'm getting color in the bottle with the clean lacquer thinner. What the heck? Oh, and I'm at about 35lbs pressure, recommended in the airbrush instructions (yes I still have them ;D ) Help!
