Wing Tailing Edge

[P Johnson]

Do you prime the the inside of the aluminium trailing edge of the wing and if so do you do this before or after you fit the optional stiffeners?

I can only say what I did, which was to etch and Alodine every aluminum part going on the plane including the trailing edge pieces. I did primer (2k rattle can) the outside of the trailing edges because my fabric system strongly suggested doing so for adhesion.

No, I only primed the outside. If I was in a humid seacoast environment I would have primed the insides.
