Roughed up and cleaned all residue with acetone in prep for sealing. Mixed up a 130 gram batch of proseal and loaded it into a large syringe. Same procedure as with the Left Tank adding a bit more Proseal on the End Rib Aft Flanges (where I found that pinhole leak on the Left Tank). All rivets were driven (160) with Carol's help. She insterted the rivets and I followed with the squeezer... big time saver.
