Not sure of the strength it adds, but the wing sure is solid. The thin ply leading edge was coated inside prior to laminating to the ribs. No drop at all when wash out block removed. I used West System to laminate parts and rather than letting the leftover cure in the can, I coated parts of the wing with the left over. When I was done and had to coat the remaining parts, only 1/3 of the wing needed coating. The wing is very strong and very light weight.Marty, what kind of strength do you think that adds? I know my sleigh runners gain a bunch from coating with West System....

On a side note, when I talked over my decision of wood vs metal, my mentor asked why metal? He pointed out that there is no issues with dissimilar metal corrosion when working with wood. Take a look under the hinge on a Cub aileron or flap when recovering and you will find corrosion between the steel hinge and the aluminum spar. There are issues with wood for sure but with epoxy, water isn't one of the issues.
