I missed the thread. I didn't search. sorry. Is this where the tip has super glued sides to prevent mushrooming?
OneIron, that is a good idea. The thin will wick deeper into the leather of the tip than gel will. And CA is a curious substance. It is a solvent for itself. So the gel will actually dissolve some of the thin and make a good chemical bond with it. That's why it works so well. The thin gets deep into the tip. The gel makes a great bond with the ferrule. You win! I hope I made that easy to understand.

PS: The thin is very brittle, and gel is not nearly as brittle.
I once used thin cyanoacrylate on a porous ElkMaster tip that turned into a wick and it turned hard. After a few break shots, the tip started to crack and chip apart. The gel is better.
