3M Windo-Weld Super Fast Urethane part number 051135-08609

Found at AutoZone or other automotive outlets. It is used on todays 
windshields to glue them to the frame. Car nuts use it for filling 
factory motor mounts to make them solid.

It'll pot anything you want and yet still be cut out if you want to get 
it out someday. Epoxy is near permanent. This stuff is wicked tough but 
can be carved out with very sharp knifes.
