The interiors of the wing assemblies should not require much caulking as the LEDs associated with them are mounted on plugs and should be largely external. I'll still spray the interiors black just to aid in painting. Similarly the upper superstructure is separated from the main hull and should get the same treatment as the wings. Once the caulking is finished I'll start on the cockpit detail. My initial idea is to start with a land speeder cockpit. It should get painted, assembled, and illuminated prior to installing it in the hull. Prior to affixing the cockpit the lighting harness will have to be installed.
Finally is a shot of the Codex binding for the Arbites Army. Its a great job and will be fun to work with.
