With having the "Feel" of the wing riveting dialed in. I started in on the right wing (bottom, inboard) skin. I was eager to get this done as its a bit tricky. I'm very much stiff and sore from all the contortion needed to reach all the rivets.
For some reason I found the right side, just a bit more tricky then the left.
One of the items that I needed to do was to use some proseal on a bent rib flange. I had bent this flange when clecoing the skin on earlier.
EDIT - Tip...This method doesn't work. The proseal doesn't hold well, and trying to reach in after to re-apply proseal or epoxy just makes a giant mess. The best method I found was to use a couple of layers of cardboard on the bucking bar when you go to set the rivet. The unset rivet pokes through the cardboard and allows the flange to press tight back to the mating surfaces. When you shoot the rivet. it's perfect!
