Well, after coating the trunk (mostly - I failed at that too) I poured some vinegar on the board to see if I could make it soft and tender, well, maybe oxidize a cool green. That didn't work.

So I tossed it back in solution after fixing the leads and re covering them with glue. I dialed the voltage down to 2v to over-compensate for the lost surface area from painting the trunk.

I think after the fresh coat of copper I can unhook the power and it should green up like last week.
