Reply to "Electronic Rust Protection"

What you are talking about is called cathodic protection, and it is commonly used on large ships, piers, and other large metallic structures that are in contact with salt water.

The theory is sound, as a sacrificial node is used, and in practice it works just fine on the structures I mention above. But I have not heard of any independant reviews of it in an automotive application.

The chemistry behind it is pretty straightforward, but if it really worked as advertised we would have hear more about it a long time ago. So I wonder what the problem is?
