Would sacrificial action be appliable? Magnesium blocks are sometimes

Well, I doubt if this could be put to use for Tom. Some of the
sacraficial methods actually use a reverse bias to combat not only the
anodic reaction, but currents that occur naturally or flow between
service grounds.

Yeah, I can't see a way to work it either. It would be a great method if it
did.
