Electronic Rust Proofing

[thebigbr]

hey all,

I hope this hasnt been covered before on here, did a search found nothing.

I saw a Canadian Tire (canadas version of something like pep boys or auto zone) commercial on TV, they are a fairly respected retailer and were advertiseing an Electronic Rust Proofing Devise.

Essentially what it is, is a box you plus in under your hood and through electrostatic current it rust proofs you car, keeping oxidization from happening. I was just wondering if any of you have come across it and what you think of it. Like anything like this i am very skeptical, but it seems many reviews have been done on it, and respected retailers are selling it. But that doesnt mean it works.

let me know what you think....any electrical engineers or chemical engineers out there that can shine some light on this subject?

here is the links to some of those products...

I've seen this used extensively in Japan and it seems to work. My buddy's 89 Skyline had no rust on it anywhere.
