Is there a list for the best airbrush psi for the different paints like laquer, acrylic, oil based enamel etc?
I have everything except the regulator now, i want to get started practicing.

After checking around, the best I can come up with is:
12-14 psi for laquer paints on lexan, thin about 50% laquer thinner *
many different things have been listed for thinning, like 4o9 cleaner, acetone?

60 - 80 psi for acrylics. not sure on the thinning ratio, or what to thin with.

Dont know yet for oil enamel, I have been using about 28 psi and I dont think it is quite right. Of course, it could be me since I am new.
Thin enamel about 40% paint thinner. Havent seen anything saying exactly what psi to spray with.

This info came from several sources, like the testors airbrush thinner bottle for example. If anyone wants to chime in, feel free! I am sure some of you know better. It would be nice to have a clear list for these.

I use Testers enamel paint and thin it with lacquer thinner, 50/50 mix and 30 psi works for me . Try it on a cheap kit .

That will depend on many factors, including personal preference, thinning ratio, equipment etc.
In my case I use 20-22 for lacquers, 22-25 for enamels and 25-30 for primers.
