I mixed 50 grams of pro-seal for today's job, rivet and seal the inboard rib of the tank. This is the last rib to be done. Riveting rib to skin went well, all shop heads look good. However, the AN470AD4-7 rivets called out for the tank attaching bracket and reinforcement plate look a little short. I went ahead and used -7 rivets anyway. The load at this location will be primarily shear, little tension load is expected here. With 6 rivets, it is plenty for even 9g load.
