I see a lot of folks fill in the exposed parts of end ribs, e.g. at the end of the horiz stab or the counterbalance rib for the elevators. Since the only examples I've seen have been painted, I can't figure out what was used to fill in the space and seal it. Foam, epoxy and glass ? What kind of foam ?

What I did was quite different. I fabricated aluminum plates on stand-offs. It was a lot of work, but they are removable and I plan to do an A/B test for drag reduction and control feel.
Yes, I have pics! see half way down here: http://www.vx-aviation.com/sprocket/empennage.htm
