For sure an alodined surface is more corrosion-resistant than bare,
but merely installing the pushrod will abrade some off. Except in
salty environments, the aluminum bits inside the wing will not corrode
into an unairworthy condition for a long time if ever. I did paint
them all for cosmetics and for ease of inspection. Access thereto for
thorough looksee is not easy, so on mine it was paint and forget.
Of a bit more concern to me were the SS rod ends in the long pushrod
and galvanic corrosion. Not too bad galvanically, but I assembled
these with wet zinc chromate. That kind of damage cannot be seen until
it gets bad.
