Ribs ribs ribs.
Fluted all of them.. tried to do many gentle flutes in the center of the ribs, rather than just a couple big flutes.
Etched and primed all the ribs. Also just sprayed some primer on the main spar. I did not prepare it in any way. If the primer sticks, it sticks.. if not.. then .. it'll just flake off.
As it turned out (me from the future), there were some spots on the left main spar that flaked off over the winter. Most of these spots were the pre-riveted bare-aluminum flanges. I tried to rough them up a bit and spray a little more primer. I doubt it will stick.
