Polyesters will not bond metal (not for long or very well anyway). 
You do need epoxy or a ca type adhesive. Epoxy should be the longer
cure types not the 5 minute stuff. Scuff the copper with some 
220 or 180 grit wet sandpaper and wipe down with acetone to remove 
the gunk. You can also use those green plastic brillo pads found in
the kitchen, just make sure they are the soap free kind.

Copper, epoxy and frp boards bond pretty nice.
