if you can try to bevel the edge so that the epoxy get pushed back into it and seal it better.

It's a tricky join, what I usually do is make a mould around it and pour the epoxy in to surround it completely, a bit like the "tee" section where the magazine meets the barrel of my marble autocannon:

if you're need to stack more epoxy on it's easiest to use something thicker like JBweld or JBweld puddy, I'd put a thick layer of jb weld around that area
