Brief Description: Riveted the left fuel cap flange and drain.
I back riveted the fuel cap flange and the vent line retention clip to it. Then did the low point tank drain. I used a Popsicle stick to remove some sealant between the shop heads to allow a clear channel for water to get to the drain hole. And finally, I sealed and set a 3/16” rivet in the aft tooling holes in the most outboard left and right hand tank ribs. Finally I finished up by using MEK to clean up any sealant that went astray. Overall, this was not a bad experience for my first real go with tank sealant. The Semkit gun application method made it a lot neater and maybe quicker as well. One 6 oz tube did the stiffeners, tank cap flange, tank drain and two 3/16” rivets for the tooling holes with about ½ to 1 ounce left in the gun. I put the remaining sealant in the freezer which should give it about 4 days of life.
