I was going to say 'search' but then I did and 99.5% of google hits are from the company themselves or copy the brochure from them.

Oily spray-on coatings on a clean car will do more for you than this thing IMO. You aren't driving a steel boat in the water, you're driving a car. Rinse the undercarriage when you can to get salt off the bottom of the car, oil it, and that's about as good as you are going to get.

Snake oil. Rust is also known as Iron Oxide. Iron with an extra Oxygen particle, not iron with a valence atom. Removing the valence atoms does not stop rust. They have alot of science on their site, but it's the wrong concept.

You could put on some zinc tabs like they do for the locks (the kind that raise and lower water levels) but it would only work in a particular area.

I have installed a couple of these. Interesting to note that they mainly go in the engine bay. I dunno I'm definetly on the fence. I have seen success, but I have done some intense undercoating jobs that swat couldn't get through. I do hate working on undercoated cars though ahhhh fark!

depending on something like this to make sure it doesn't rust is null. only good ole fashioned elbow grease and knowledge of salty roads is the key on this.
