Touched up a few missed places w/DuPont Primer (215S). Placed rivets in one stiffener line on skin and riveted 3 rivets using back-rivet set before realizing that I never laid the stiffener in place. Drilled them out! Proceeded to rivet all stiffeners onto rudder skin. Used masking tape to hold rivets in place after sticking tape onto my shirt 3-4 times. Using AN470-AD4-4 rivets and pneumatic squeezer, riveted top row of rivets on R-606PP, R-607, and R-608 reinforcement plates to R-602PP spar. Riveted platenuts to spar and R-607 & R-608 plates using AN470-AD4-5.5 rivets, cutting -6 rivets to size for proper shop head size. Clecoed rudder horn, spacer, and R-404 rib to spar & R-606PP.
