I simply put the vaseline on the joint-plenty of it to be sure.

Then i use 30 minute epoxy into the hole, then insert the hinge. I use just enough epoxy until its just spilling out.

seems to have worked fine so far.

I have found that if the epoxy does dpill out excessively, its better to let it set in a dollop, rather than try to clean it all up and spread it around before it sets.
