Not much visible progress for today. I wiped down the inside of the right tank with MEK after vacuuming it out. There were some metal shavings left over from drilling for the return line that got stuck in the sealant. I then went over all the filet and fastener seals and did some touch up with sealant on anything that looked questionable in preparation for sealing this thing up for good. Finally, I riveted in the flop tube anti hang-up bracket that bridges the rib and stiffener for both tanks.
