I've been inactive for several years, but am getting back in the game. I want to weather some of my model rail cars with my airbrush and need a refresher on what air pressure to use. I have a Paasche VL airbrush. I have some Floquil paints I'd like to use, and when my supply runs out was planning on switching to Modelflex acrylics.

What pressure range should I use for Floquil? Memory seems to tell me 20 to 25 psi. What pressure should I use with Badger Modelflex? I saw one recommendation of 25 to 30 psi.

All advice will be appreciated. Thank you!

i use 15 psi or close to that ... but my paints [mostly krylon] are thinned and kinda runny .... less pressure and thicker paint for weathering, i like that it goes on a bit unevenly ..
