Thanks for all the quick responses, links to articles and details of your
experiences removing "the devil's glue."  It really helps to have the
collective knowledge and research of the group!

I ordered some Marine Formula DeBond and a razor blade scraper knife.  I
also made a wooden wedge and have a rubber mallet ready for some *very *gentle
taps after patiently waiting for the adhesive remover to go to work.  The
DeBond should get here on Friday so this will be a weekend project.  Until
then, I have other boat projects underway to keep me busy when I'm not at
work.

I'll be sure to follow up this weekend and let you know the (hopefully not
gripping) conclusion.
