Hmm, I think I'll stick to the Arctic Silver stuff (or equivalent). I'm sure some epoxies with the oxide powder would work well, but seems to be a little easier to use the stuff created for the purpose rather than figure out how much powder to mix for good heat transfer while maintaining a good bond.

However, I would not use JBWeld as the base as that stuff is definitely meant for permanent bonds. With the thermal adhesive, removal is still relatively easy when/if you need to.
