I wonder how 3M 5200 compares to adult barnacle attachment secretion which is nearly impossible to break.

Maybe Debond would work on barnacles!

Mark: I wouldn't even use it for the hull-deck joint. In fact I had to break the seal to remove the foredeck on my boat. I may be the only person to ever do that but still I don't think anything is permanent. 5200 and similar are incredible adhesives but if you are primarily interested in a sealant where high adhesive qualities are not the highest priority and if there is any possibility that you might want to break the bond in the future, I would always seek an alternative. 3M 4200 is a very strong adhesive but is easier to remove.

I've read that if you take a strong, thin wire like piano wire you can slowly cut through the 5200 (AKA Devil's Glue). Don't know if heating it would help. I've never needed to try this so if you do let us know how it goes.

About the only legit use I've heard of for 5200 is a hull-to-deck joint.
That's something that you hope you'll never have to disassemble.

Good luck,
