Left Tank: Cleaned up the tank....scuffed the mating surfaces....marked fay-seal boundaries with electrical tape.
Took a while and was not enjoyable. Marking a nice consistent boundary turned out to be harder than envisioned. I toyed with the idea of throwing caution to the wind and just breaking out the ProSeal, but there was no way I'd be here two days later to rivet.
I plan to go back on Monday. During that session I'll probably work more on the inboard rib and drill/insert the fitting for the vent line.
