Thanks I am unsure about the best way.If you plan to use a tank sealer, do so before painting. And all of the Bondo - type fillers say to apply to bare metal.
Bog on bare metal is sort of old school because moisture can still be a problem, so it's often used on epoxy primer now but many fiberglass fillers are water proof.
Maybe I will skip the fiberglass filler once painted with epoxy.
I might do most the prep and finish painting after the sealer?
As you know this is not my forte so if there is a flaw in the plane please let me know
