    I'll have to get to the hangar to see specifically what I used. I did not epoxy as I was trying to avoid painting in my attached garage and I don't expect to be spending a lot of time at the beach.

    Thanks for checking. Meanwhile: did you do anything for the outside of the spars, or just leave them alone?

    I primered mine with epoxy primer with a brush. Aviator79 did the same I believe.

    Some primered the inside by inserting a tennis ball in one side (press fit), loading primer, then ball in other end and then rotate wing.

    So this is a timely discussion for me. I will be starting my rebuild of a Kitfox 4 that I intend to someday put on amphibious floats. Although I live in Illinois where corrosion isn't as great of a concern, I want to do what I can because my retirement plans include going to coastal areas and splashing around. Given that the wings are already assembled and in good shape, what is the consensus regarding corrosion protection I can use that would be effective without having to take things apart on the wings? Is there something that can "creep" into the joints?

    I just Alodined them inside and out. Light weight and a somewhat easy application.

    A two part epoxy coating would be the gold standard in an harsh environment, just heavier.

    Gary, were you able to find out which product you used and how much you needed?
    Thanks
