It seems that I am learning how to work with this sealant stuff (black death) fairly well. Tonight I riveted the skin stiffeners, fuel cap flange, and drain flange all in one sitting. On the left tank it took me two nights to get this far, so moving faster and getting better results with this tank.
I still need to dab a bit of sealant over each rivet head and fillet the edges of the stiffeners, but things are going well so far. Tomorrow I will dab the sealant as well as seal up some of the items on the end ribs.. You can seal the vent fitting, sender BNC fitting, fuel pick up and outside edge nose stiffener prior to final assembly so going to get that done all in one sitting as well.
