I noticed tonight that my Avistar's vert stab was flexing to one side more than the other. I then noticed the bead on epoxy on one side was cleanly lifting off the fuselage. Originally, epoxy was put inside the slot, but a bead was put along the outside too. I think the mistake was that the epoxy along the outside was glued to the covering, not the wood. The epoxy holding it in the slot is wood-epoxy-wood.

What is the best way to fix this? I was thinking of removing the old bead of epoxy (what would I use?), removing a few millimeters of coveruing off the fuse parallel to the v-stab, then putting a new bead of epoxy there.

I don't see needing to remove the entire v-stab and re-attaching it. hmmm. Any thoughts on this?
