Jason,
I'll second lewbud's comments.
Typically I'll
1. Airbrush the base cockpit color, as Interior Green.
2. Hand paint the black boxes and control panels.
3. When everything is the right color, I'll give it a good sludge wash to highlight the panels.
4. From there I'll do some light drybrushing and add the details like silver to levers and switches, red and yellow to buttons and lever handles, etc.
5. Finally it all gets sealed in with a flat cote.
Just use your own evaluation along the way as if it's done "right". After all it's your model, so if you like the look, go with it.
