Yepper, super glue, epoxy and... clear enamel? Cool! I never thought of that!
Another thing I use that's more suitable than one might think is plain-'ole craft glue. Basically the same as white glue, this stuff dries to a rubbery consistency and will not lose it's grip on the PE, even if the model gets jarred.
Many times a few models have gotten tossed around in the car on the way to a show because of someone's stunt driving and the other guys had broken pieces when we got there. I've had really good luck to this point with craft glue and breakage, or lack thereof.
Th downside to using this stuff is the slow drying time. Other than that, it's almost perfect for most brass applications.
