When painting with an airbrush, which type of paint do you prefer and why? I'm not talking about different brands or colors but simply, water based or thinner based. You see, today I tried out my new airbrush with some thinner based paint. While, I loved the results, it stunk (for quite a while... in fact it still stinks), it made a big mess that I had a heck of a time cleaning up, the thinner costs a lot more than water, and... did I mention the big mess? I much prefer the water based paints but I have not done that much painting with them and I wonder if it will stick as well as thinner based paint. My next painting project will be rusting my rails and I'm not sure which way to go.
