Thank you John, Roger, Calum and Peter for your replies. Peter's may not have been helpful, but was still a pleasure to receive. Calum's makes me think that if I can keep the wire free from saltwater it may check electrolysis more than an anode. Guess I can try an anode and see, even though i hear whatRoger had to say. Or I just let it rip, and buy new wings later. Maybe CRC......
