Today I started off by dis-assymbling the left tank and cleaning all parts with MEK. I then mixed up a good batch of proseal and spread it on the 5 inner rib (L2-L6) flanges one at a time. I inserted each rib carefully into the skin and put clecos in every hole. I then clecoed in the L1 and L7 end ribs for fit and form. I cleaned up all proseal smudges from skin. Clecoed in the rear baffle for fit and form as well. I'll let the proseal cure for a few days then Andrew and I will install rivets on the 5 inner ribs.
