Hi guys, a quick question... Recently I've remembered something I've always had issues with. How do you go about priming and evenly airbrushing very deep detailed areas? I find its do-able but I tend to end up wasting a lot of paint in the process because of the kickback from the spray. For example...

The yellow areas... There's plenty of ridges and a lot of small details where when I spray with my normal PSI, the spray tends to kick back a lot. Also its a deep depression so the paint doesn't have an open surface to cling to easily... I find I end up angling the parts in to all sorts of weird angles to reach different areas and getting an even coat is very difficult. I have tried 2 different methods so far, with mixed results. First method was to lower the psi, thin the mixture more and spray very very light coats further away from the part, building up layers and colour very slowly. This has worked but sometimes I thin the mixture too much and it doesn't dry fast enough so it starts to run on the surface. The paint goes on unevenly as well since its primarily the very raised areas that gets the majority of the paint, and the very low/depressed areas gets very little. So the paint job isn't as even as I'd like it to be. (Perfectionist.
)
2nd method I've tried is to use my normal, milk consistency mixture and to increase psi, but instead of a normal stroke I move the AB in close and "blast" the paint in, covering as much surface with very quick, sharp blasts of air. This hasn't been as successful, as sometimes the paint can collect and give me drip or a sagging paint finish.
I was wondering how you guys tackle bits like this. I find I have the same issue when airbrushing the inside of thruster wells and gun/bazooka barrels too. Can anyone share they way they deal with these kinds of parts?
