I will lay down the basic interior color either with the airbrush, rattle can, or by hand-brushing, and then detail by hand. There is no airbrush technique that I know of, that can paint the detail of instrument dials, for example, or paint the colors on throttle quadrant lever knobs in 1/48.
Regarding the instrument panels, I don't use white glue, but Future, to recreate the glass covers. I'll paint the panel the base color, usually black, and then drybrush to pick out raised detail, the add a drop of Future on each dial. If the panel is a decal, I do the same thing, a drop of Future over face of each dial.
