I've got the cockpit tub on my Corsair mostly painted. Right now I'm waiting on replacements for the pilot's seat, rear bulkhead, and a part to fix to the front of the flight stick (the former two were broken, the third was missing). Once they come in and I get them painted I'll post some pics.
One thing I'm doing, in addition to dry-brushing aluminum for wear, is giving a light wash of thinned Polyscale "Dirt" on the cockpit floor. This adds to the used appearance of the cockpit, and helps tone down the color.
