I was able to complete painting the rivets inside the golf club extension this morning, I'm undecided as to lining the rear wall with semi-rigid foam as protection from damage caused by loose items finding their way back there. I deburred & primed the belly skin & installed thick sound proofing foam for lining the bottom of the unused main gear channel. A trial fit of the channel & ribs shows at least 9 holes (in deference to the golf club extension I wonder??) are missing from the belly skin. More match drilling required.
