Since I'm still allowing the fuel tank proseal to set, I decided I may as well get on with prepping the bottom skins for priming. I'm still feeling uncomfortable about the [non-]sealing of the screws holding the fuel tank access panel on. I've thus decided that when I mix up a batch of proseal to do the wiring conduit and vent, I'll remove and replace the screws with proseal. Any screws that get munted I'll replace with new ones. I'll feel much happier then...
