Two Guys Garage has advertised several things that are "gimmicks" including the Tornado air filter insert as well as the electronic rust preventative.
The following is from the FTC web site and is a ruling about one of the "Electronic Rust Prevention" companies:
RustEvader Corporation (a/k/a Rust Evader Corporation, d/b/a Rec Technologies)
The Commission issued an order making final an initial decision by an Administrative Law Judge in regard to RustEvader. The initial decision prohibited RustEvader from using the names "Rust Evader" or "Rust Buster" for a purported electronic corrosion-control device for automobiles that the Judge said is not effective in substantially reducing corrosion, despite the company's advertising campaign to the contrary. The Commission alleged that RustEvader made false claims about this product and about a demonstration and studies regarding its efficacy. The final order prohibits RustEvader from using the two brand names; misrepresenting the performance, efficacy, or attributes of any automotive product; and conditioning warranty coverage on the purchase of certain brand-named or trade-named products or services. The former president of the company is also required to pay consumer redress (see RustEvader Corporation, page 87).
That pretty much tells me this method of rust prevention doesn't really work. As for the Tornado... A fool and his money are soon parted.
