Finally got to experience the joy of working with Proseal. It actually isn't too bad if you're careful not to put too much on. Proseal is used to hold the trailing edge wedge in place and keep the trailing edge straight during final riveting. The stiffeners were riveted together joining the two skins and the bottom rib riveted to the skin. The trailing edge was all clecoed together to hold it tight while the proseal cures.
