The silicone method sounds the easiest. I was thinking about using some micro balloons mixed with epoxy, squeeze it between the gaps then let it dry and grind off the excess and that would give me a hard surface that wouldn't flex or come off. Anyone use that method.
I haven't done the epoxy thing, however I do use balsa filler with saran wrap to "true up" the wing saddles prior to covering. Covering OR paint will not adhere to the silicone.
