I have this radiator I want to use, but the inlet and outlet were huge. So I cut them off leaving about a 1" collar. I had intended to solder my brass barbs onto the copper collar. However the moment I began to cut, it was obvious I was cutting plastic. The top and bottom of the radiator are plastic.
Well, solder is out of the question now. Should epoxy hold the brass barbs in good enough? What kind of epoxy would you use? I have 5-minute clear epoxy and some cool plumbers epoxy that comes in a stick that you mash up like playdough and stick to things (best for metal). But I'm not sure what will hold to this black plastic that the top and bottom of the radiator are made of.

Has anyone else come across this?
What worked?
