Snake oil!

Electrochemistry has been part of my schooling. I've actually done some research on how to protect cars from corrosion. Corrosion protection by electrical potential has been used successfully by the marine industry to protect ship hulls and has been used on underground pipelines.

In theory it can work on cars, too, but a couple of things would make it impractical for use on an automobile. An electrical potential would have to be applied constantly in corrosive conditions with consumable anodes on the vehicle. This would drain the car battery in short order. Any anode placed on a car would protect only for a finite distance, depending on potential strength.

The key to good anodic protection would have to maximize the following conditions:

- large anode area
- large electrical potential
- short distance of protected metal from anode.

Auto manufacturers spend millions on research and thousands of dollars in manufacturing costs for each car to protect it from corrosion. They've really come a long way since days of old to protect cars from corrosion. Do you really think they'd ignore this type of system if it really worked? I lump this product together with the 200 mpg carburators that auto makers supposedly suppressed from the public twenty years ago.

Stick with galvanized sheet, phosphate coating, e-coat primer, and Texaco rustproofing compound to maximize corrosion protection for the sheet metal on your car.
