I have an Aztek A470 airbrush that I want to start using. However, I can't seem to figure out where I put the users manual.
What PSI do you fellow modellers use?

PSI is directly related to the viscosity of the paint. Unreduced model paint has a higher viscosity than reduced paint and requires higher PSI to atomize properly. Reduced paint has a lower viscosity and requires lower PSI. In general start with a PSI of 15 - 20 #s with the paint reduced 50%.
Hope this helps,

When I use my 470, I thin Tamiya paint 50/50 and shoot at 10 PSI. I get less overspray that way.
