The big decision was whether to paint the interior pieces that show at this time. After much hemming and hawing, I have taken other's advice and decided to prime everything as I go and then re-prime and paint once the fuse is together. The crevices in seat back brackets will be hard to get to once assembled, so I will leave those cleco'd for now; those will end up having exposed rivets. This plan prevents me from having to worry about scuffing the paint during the build.
So the fuselage bulkheads are ready for assembly. The decision to prime did not add too much work, but it did add confusion. The various steps to prep the bulkheads had to be stopped while I built up a stack of parts to prime. This priming session was a long one, but went fairly quick.
