Today I riveted the reinforcements to bulkhead #4, and primed the aft left and right skins around bulkheads 4 and 5, and the rudder cable slots.
I will either be painting or covering the baggage area with a light carpet for appearance purposes. In either case the baggage area needs to be primed. Formers #1, #2, bulkhead #1, the tail cone stiffeners, and the elevator push tube enclosure sides and top were all primed on the visible surfaces.
