I am wondering how far to go with epoxy primer on bare aluminum. I am primering critical things like wing spars and braces, trailing edges, etc. But what about things like console top and sides (will get covered with carpet), console undersides, flap detents, rudder pedal brackets, fuse framing for door, tail access cover insides and flanges, side & bottom stringers, instrument panel backside & supports, etc. I know anything that will get painted needs a primer coat, but my main question is stuff that normally is left unpainted and backsides/insides of less critical things. I do not intend to operate in a salt water environment.
