Epoxy does not adhere well on oily and porous wood. Traditionally, acetone
is used to remove oxidation and natural oil before using epoxy. Even at
that teak and oak need mechanical devices (screws, dowels and joinery) to
provide a good bonding.

Hmmmmmm I think you should tell the Gugeon brothers about this because
they might find all of their beautiful yachts are falling apart.
I suggest you get a copy of their information pamphlet from Lee Valley
Tools and read up on West System Epoxy
