Blew out dust and overspray from priming in the right wing for the last time. Spot primed csk holes in in spar flanges; sanded edge of inboard skin for smooth transition where the outboard skin overlays it. Primed the sanded areas.
Laid out the rivet line order and started with the rear spar. Karl shooting, Kurt bucking. Finished two bays and Karl had to go in to work.
