Electronic Rust Preventers

I just bought an '86 Nissan with a little bit of rust. I would love to make this car last and was wondering about these electronic rust preventers/stoppers. My dad bought a new truck and that was all they put on it to keep it from rusting (no undercoating) and they make claims that it should keep a used car from rusting further. Is it worth the $150 or so?

I have heard of these things for a while, but I never knew anyone that actually used one. I always wondered if they really did work. It has some physical merit. From what I can remember about my chemistry, it sounds viable. If any of our readers have one, or know of someone who does, then please let us know. Also, if someone has a reason why it does NOT work, then let me know as well.
Good Luck!
