Brief Description: Riveted Rudder skins to stiffners
After removing the vinyl from the rivet lines and applying Dupli-Color Self-Etching Primer for Aluminum, I back riveted the left rudder skin and stiffners. Then while riveting the left skin and stiffners, the back-rivet set slipped off the back rivet plate, splitting the skin and "denting" the stiffener. Decided to order a replacement skin and stiffener rather than stop drill and fill.
