Thanks mate - I'll do some more experimenting, it can't be that hard. I've got a compressor with a moisture trap on it and that seems to be working well enough, it's just getting the correct pressure level, the consistency of the paint and other things like which needle and tip to use. As Jason says, I'll just have to get some inexpensive paints and blast it on to sheets of paper while I work out what's what - the Tamiya paints are excellent and give a perfect finish for warbirds, but are too expensive to use for experimentation.

Thanks gentlemen - I'll get back here with some results after I've made some progress.
