Vallejo Model Colors in Airbrushes - Got burned once. What am I doing wrong?

[RuneBrush]

Had another quick question. My HP-BH air brush came with a spray sample sheet of paper in the case. It has an amazingly thin spray pattern. I haven't needed to do anything detailed, but before I start poking at the air pressure etc to figure out how to get such thin lines I thought I'd ask you knowledgable fellows.

My HP-C+ did as well - I've a feeling they must have put ink through it rather than paint. Quite low pressure too (5psi?)

Iwata does that with paint for all, or at least most, of their brushes.

Fine lines come down to trigger control, distance of the nozzle from the surface and the paint mixture (it's got to be thin enough to pass through a very fine hole in the nozzle). The PSI isn't so important, but if you lower it a bit from what you're used to using, it lets you go a little slower and still avoid spidering and drips and such. The paint shoots out of the nozzle in an "X" pattern, you want to have the surface right near the nozzle where the paint is at its thinnest, before it spreads back out again, it's quite close and that's why so many needles get bent.

Thin paint & low pressure.
