Hasn't seemed to work when I've tried it.  I normally use either
soldered eyelets or thin wire and solder.  Solder "wets" metals to
adhere, there's nothing in there to adhere to.

I think that it's a conductive epoxy, so there's a limit to how good a
conductor it is.  People have used windshield heating element repair

I've seen graphite used, but that's before copper plating.
