RMweb Premium Trainshed Terry Posted January 15, 2021 RMweb Premium Share Posted January 15, 2021 I would like to use Railmatch acrylic paints with a air brush, since that it is getting difficult to get rattle cans of paints by postal services. Can someone advise me on what is the best way to thin these paints to use with an air brush, and what is the best air pressure to spray at would be.

RMweb Gold Mick Bonwick Posted January 16, 2021 RMweb Gold Share Posted January 16, 2021 (edited) Thin with acrylic thinners, either Railmatch's own or Ultimate Acrylic Thinners. Thin to the consistency of milk, i.e. when you agitate the mixed paint in the airbrush cup it doesn't stay on the sides nor does it fall back immediately. Try agitating some milk in a glass to see what I mean. According to your airbrush, compressor and paint consistency, somewhere between 15 and 18 p.s.i. These are my own opinions. Others may differ!
