>>> Un-Hesive – 3M 5200 remover?

If you have worked on or around smaller boats any length of time, you have probably encountered 3M 5200 or similar adhesives. This stuff is great… sticky and holds seemingly forever, which is great, until you need to remove it.

Un-Hesive claims to be a remover for these types of adhesives, and in DIY Boat Owner’s review, it did seem to work. Might be worth a shot.
