HAH, u want to see a bonneville with rust issues?!?!?! come check out MY RIDE! haha, if rust issues were a psycological problem, my car would need Dr. Ruth, Dr. Phil and OPRAH, teamed up...i wish someone knew about this in 1989...

It'* sounding like this device could work. I agree that a quick test would be to put two similar pieces of bare steel outside for a few days, one with the device. WIll be able to tell a difference pretty quick, if there'* going to be one.

I'm not gullible (Tornado intake, etc) but I'm open to new ideas

Hey, now, I didn't say there weren't ANY BVilles with rust. Just doesn't seem to be a chronic problem (i.e. UIM'*, and LIM gaskets, etc...). :P

Would be a pretty interesting experiment to see the results though!

The late 80s Bonnevilles saw a lot of rust, mainly because of the how it was designed. There are still a lot of 92-95 models with rust on wheel wells. My last one had a bad rust spot on one rear quarter panel. Newer cars are designed better so they won't rust as easily, but with time and especially salt in the winters, it could still happen, especially the undercarriage of course. I'm pretty sure these devices are supposed to protect ALL the metal, so it may indeed help with the undercarriage.

Hate to tell you, but most cars from the past fifteen years lready have something like this in them. Basically, all you have to do is weld a piece of zinc to bare metal. That'* one of the many things that helps modern cars last longer before rusting under the same conditions.

Should never have to replace the anodes. Zincs had to be replaced. (what remained of the zinc)

This will not work. You have to have an electrolyte between the anode and cathode. Air is not a good electrolyte. The only way I could see it working would be if the anodes were on the outside of the car and during a heavy rain the water made good contact between the anode and the steel. It would only protect areas within the continuous contact area. Steel with a single drop of water on it, and the water is not touching he anode, will not be protected.

Any anode will have to be replaced. A galvanic system is driven by the natural potential difference between the metals. An impressed current system forces one material to become the anode and another to become the cathode. Either way the anode will be consumed at some point and need to be replaced.

where'* mythbusters when you need them

Call it in Rob..

til then...I'm believing the ship/sub builder with years of experience in salt water.
