Oh i didn't fear any problems with the resistance. i do not expect it to
be significant.
I just feared that the etchant will eat away the copper i plated.
just like it is supposed to eat away the copper from the pcb.
I guess you definitely need to take out the electrodes, or at least remove
the
copper if you disconnect the power source for a while.

Have you measured which current/voltage you use? would be very interesting
to know that
and maybe also the estimated electrode surface, and the bath volume, and
electrode distance.

thanks a lot...
