Actually, the vast majority of waste is on the interior (not-end) ribs, & the stiffeners. The only place the tank can leak is through the rivet holes, so the only sealant that matters is in the hole, and for insurance, a little 'donut' of sealant around the rivet between the faying surfaces plus a small dollop over the shop head.
I wish I could claim 'brilliance', but I was taught by a 2-time builder.
