Applied the Proseal to the trailing edge of the Right Elevator

The first thing I did was to put a small chewing gum size wad of proseal between the ends of the stiffeners where the come together at the aft end of the elevator. This will keep the stiffeners and skin from moving up and down and cracking the skin. I saw an RV-9A a couple of weeks ago where the skin had cracked between the stiffeners and the trailing edge. The owner had to drill small holes in the skin to shoot proseal in, to stop further cracking. Then I put a 3/8 inch dowel rod into the opening to hold the skin apart so I could apply the proseal to the bottom skin. Then I put a layer of proseal on the top of the aluminum wedge and put it in place. Then I slid the 3/8 inch dowel out, allowing the skin to close in around the aluminum wedge. Then it was just a matter of clecoing everything down to the large aluminum angle.
