I finished deburring the stiffener and peeled all of the protective blue film off of them. Also started doing my donut hole removal of the blue film from around each of the rivet holes on the outside of the skins. I also peeled the film off of the leading edge of the skins where they will eventually overlap. There are a lot of flippin' rivets on this rudder. Hence about a billion little blue donuts. I think there are more on it than the horizontal and vertical stabilizers combined.
