I unmasked the primed lower skin and began installing it this evening. I got all the bolts and rivets installed, but left out the aft row of the fwd skin. These fasteners will get installed when the lower aft skin goes on. Which is nearly the last thing to be finished before inspection.
You'll notice in the picture, there is an extra AN526 bolt in the forward fastener row on the bottom skin. I got a little crazy when updrilling the motor mount fittings and accidentially updrilled one of the rivet holes. No big deal though. I just installed a shorter length 526 bolt. No one will even notice the difference and it certianly won't affect the structure in a negative way.
