I saw a ad that you can use battery energy running through your body panels and metal components to protect against rust. It stated that snow plows and industrial equipment have been using this tecnonlgy for years. Anybody hear or seen this or use this on there trucks?

 

Last time everybody called it snake oil.

I would ask somebody with a snowplow, personally...

 

Thats what I was thinking

 

There was a thread on this not too long ago, do a search for zinc.

The Navy and metal bridges have been using electric rust protection for decades. My understanding is that in order to work the object's paint must be electrically conductive so you are out of luck on most vehicles.

 

i also heard it does not work so good because of the various types of metal used on a vehicle.

 

The only way to have a vehical that doesn't rust is to get a DeLorian or an Acura NSX.
