Today I scuffed, cleaned and primed fuselage bulkhead parts. On the F-705 and F-706 I completely primed the bottoms as they will be under the floor, and will rivet to seat and baggage ribs, making it difficult to prime only the faying surfaces. On the F-706 sides, and the F-707 and F-708 I only did the faying surfaces. On the F-710, F-711, and F-712, I primed both sides of all the sheet metal parts completely. I also completely primed all of the non-alclad bars and angles. No photos - if you've seen one primed part, you've seen them all....
