Serious epoxy problems
 

First, how long did you wait between painting on the original
coat of epoxy and applying the paste? If it was too long, amine blush is a
possible culprit.

Excellent !

Second, "serious clamping" can be a mistake with epoxy. If it's squeezed out
to a layer thinner than roughly 0.003", strength falls off quickly. Below
0.002", it can all but disappear. Unlike resorcinol or some other adhesives,
you shouldn't clamp epoxy more than it takes to hold everything in place.--

This would be my guess. got to have somthing left to make the bond.
Ive seen similar effects when people sqeeze every last bit of calk/
sealant/adhesive out of a joint when bedding hardware.

Another consderatin is wood type used. the bond problmes increases
with more dense/increased mosture content/oily woods.

was it teak or white oak or douglas fir?
