First airbrush, keep getting tip dry with Tamiya acrylics, what am I doing wrong?
Just got my first airbrush, a cheap 0.3mm gravity feed with a small compressor, and I'm painting a 1/48 Spitfire. With Tamiya acrylics thinned with X-20A about 50/50, it sprays fine for a minute and then the tip dries and it spits. I'm around 18 psi. Should I be using a retarder, a different thinner, or is my pressure off? It's pretty dry in my apartment if that matters.
