My new 40 vertical suffered a failure today when the door hinge epoxy let go and it fell off while I was opening it. I used fresh epoxy glue, sanded both the hinge and plastic frame of the tank for a better grip prior to applying the epoxy. I'm looking for suggestions on how to reapply the door hinge to the tank. Is there a specific epoxy type I should be using.

I have another 40 vertical where I used a kit from AAA Frogs and that has worked just fine. The new setup is home built and follows along the same build as the one from AAA Frogs.
