I primed around the edges and along the center support on the backside of the baggage bulkhead...

...and primed the entire front surface of the baggage bulkhead. I hung it in the garage to minimize dust nibs.

Same with the upper panel of the baggage bulkhead.

I managed to get these panels primed before my batch of primer ran out. The few additional parts that didn't get primed today will just have to wait until I am ready to prime more stuff.
