Ok I'm a new airbrusher so bear with my stupidity..
I have been playing with my single action Paasche and attempted to paint a simple camo paint job on a 1/35 scale Hummer. I am having a very hard time getting the paint stream both fine enough to paint a small, precise line and still keep paint flowing thru the nozzle. Let me make that a little clearer. My brush came with a no.1, no.3 and a no.5 tip sets. I have tried all 3 and have had the best luck with the largest. I am using Tamiya Acyrlics and I have tried them both thicker and thinner. When they are thick you must increase the air pressure and turn up the needle. When I thin them down I do not get any coverage. Trying to spray Olive drab over tan would take so many coats that holding a reasonably nice edge is not do-able. As you would have to pass over the area so many times you would overspray the edge. So I have a few simple questions.
First.... Which tip size is correct for Tamiya Flat Acrylics? 1,3 or 5?
What air pressure would you suggest for doing fine camo type painting?
Is a single action brush going to be able to do what I want it to?
Do most people mask camo patterns? If so what methods are most common?
Any suggestions are greatly appreciated. It is hard to learn something like this without someone to watch do it.
