Riveting left tank interior ribs

Tonight I riveted the ribs that I prosealed into place last night. I started at the rear of the ribs and removed one cleco from each rib, put a touch of proseal in the dimple, then placed a clean rivet in the hole. Then I shot the rivet with a mushroom set and bucking bar. After shooting five rivets in each rib I cleaned the excess proseal from the outside of the tank and tools. I finished with riveting the filler and drain flanges in place.
