Prepped and primed the aft deck and the aft bulkhead. Painted the aft deck using the same "Ford Gray" color I used on the interior. The aft bulkhead will be painted much later, with the rest of the exterior of the plane.
I also painted the elevator stop and the F-810A upper aft bulkhead, and cleaned and prepped the two spacers that will go under the leading edge of the horizontal stabilizer spar.
