Just bought a new vehicle and when we were at the dealership, the dude tried to sell us some rust protection called Final Coat. This is typical, and I was expecting it, but didn't have any idea what it was. Turns out it's this electronic gizmo that hooks up to the body of the vehicle. Then it emits a tiny charge throughout the frame. This is supposed to stop rust from forming on the metal.
They charge $1700 for this thing, and it comes with some warranty and coating on the paint etc. He offered it to us for $699 - his cost, he insisted (cause a lot of costs end conveniently with 99). So as a sucker, I said ok what the hell.
Got home, and looked it up. Found this link (which might expire cause it's on Ebay) :
If the link is dead, cause the auction is over, it was a lot of 12 of these things for $10US. No kidding!! I called the next day and had him cancel that from our invoice. To his credit, he did without pressuring me.
If you want to read why this gizmo doesn't work there is a good article here. You need to scroll down to Rust Bug Killer.
