Yes to ALL of that.
I should have added, that the size of
the repair will make a Big difference if i use Glass to
reconnect the skins after the repair. Anything over the
size of 1/4" square and I would use glass.

Glass over a repair, if an 8oz were sufficient, then
i Always use (3) layers of 3oz finish glass because
it has a very tight weave and it's rather thin. the first
layer would be 3' larger than the repaired aria, the second
is 1.5" larger, and the last is 3/4" larger than the repair aria.
Large repairs need a minimum of 2" overlap to all sides
of a repaired aria to reconnect the skins.

Adding a fairing coat of epoxy with West System 410
Microlight is the ideal low-density filler to make the final sanding easy.
