Roughened up the seam surfaces on both rear baffles then washed and etched them. Wiped down seam surfaces at the rear of the assembled left tank with MEK, as well as its rear baffle. Mixed up 60g of proseal and put it into a plastic bad and cut a tiny corner off. Worked great to lay down a 3/16" line of sealant just fwd of the rivet holes. But there wasn't enough to butter the rear baffle edges and the rib flanges. Mixed ~30 g more. Should mix 100g for the right tank when the time comes.
Dropped in the baffle and clecoed everything. Had I been SMART, I would have clecoed the z-brackets on at this time. But I had to sand off the primer on their bottoms. But I finished the 160 AD3-3.5 flush rivets along the rear baffle seam first, then came back after dinner and did the z-brackets, buttering their bottoms with one more 30g batch of Pro-seal. Had just enough (with a lot of scraping) to encapsulate the shop heads of one line of flush rivets.
