I did a search on this forum (and the AU forum) but did not come up with much either.
These gadgets are not inexpensive by any means - - but it is a one-off investment and if they are any good (given our climate) they might be worthy of consideration...
Comments welcome.

Sounds like cathodic protection.
I had a similar device fixed to my '81 Mazda 323 many years ago. It used two pads wired to a black box which were attached to a bare metal portion of the car.
The device seemed to accelerate corrosion of the aluminium rivets I had on the car. It supposedly works better in a high moisture environment.
It's used in ships, and works in a way that causes sacrifical zinc-alloy anodes that are attached to the hull to corrode first.
I eventually detached it and experimented on a plate of mild steel sprayed with a saline solution - rust formed, so I guess the system didn't work as claimed, at least not without some sort of sacrifical metal attached to the surface being treated.
