how good are these devices, do they really work? I was thinking about picking one up, but after reading this article im kind of skeptical http://ask.elibrary.com/login.asp?c=...o=&refid=ink_4

 

you're asking if they really work and providing a link to a manufacturer who has to mail refund checks because they made "false claims that the electronic devices used...inhibit corrosion" ??

you're kidding, right? It doesn't work, and that article proved it.

I was skeptical because I recently seen a episode of Truck where they were winterizing a pick-up, and used a similar device. They stated that the product was tested and proven.

 

mainly this doesnt work because the technology only works on things that are fully submerged in saltwater, like bridge supports and ships. it uses a 'sacrificial anode' which is bonded to the steel, and by that piece of metal slowly corroding is able to protect the steel. on a car there's going to be wet spots that arent in contact with the anode.

they also got into trouble was offering a lifetime warranty on rust repairs for people who used their product on then-new cars.

 

seen a sentra with one, still rusty,

 

It works for things in the ground also, like pipe. It's called Cathodic Protection.

Here is a company that I found that does this sort of thing if anyone is interested...
