A while back I experimented with sealer prior to gluing parts to see if it would make a weak joint. Of course I was careful not to get sealer on root edge of the balsa parts. I glued a bare balsa fin to a body tube with aliphatic glue, added glue fillets and allowed to dry for a week. I did another fin, sealed with 4 coats of Brodak sealer and did the same thing. After a week I tried to break the fins off. Both were solid, and I could not tell a difference when trying to break the fins off.
