I would not use 5200. Dealer said to use something else. 5200 is permanent. BE REAL careful!!!

I've heard that a product called Anti-Bond, available at West Marine, is very effective at removing and de-bonding 5200.
It is if it's a thin bead of 5200. If it's a large contact patch that's filled with 5200, forget it. I know someone who inherited a boat on which the beams were seated with 5200. After trying every chemical known to man, the beam eventually claimed part of the deck before it was removed from the boat.
