Spent a little more time deburring and smoothing the edges of the skins. Prepared and primed the inside of the skins and the stiffeners. To keep the stiffeners from flying around while I was spraying them I put two nails at an angle into a piece of plywood and slipped the stiffeners onto the nails. This kept them in place while I primed them and it was easy to lift them off and turn them over to spray the other sides. After they dried I riveted the stiffeners to the skins. Using the back riveting tape worked great... back-riveting is quite simple if you follow all the steps and keep the back rivet plate under the rivets. Once the skins were done I spent about 30 minutes getting started on the Rudder skeleton. The picture of the finished Rudder skins shows them laying on the hood of my 1968 Mustang Coupe.
