Thanks for that Lakes. I actually have one of those on my i30. I first had it on a Renault Fuego...then it was moved to a Toyota Camry...then a Nissan 300ZX...Toyota Corolla and now on the i30. I never had any rust issues with any of these cars. I have bought and fitted one to the Getz too. Not sure if they work but certainly can't hurt...

sounds interesting, what's it called. 

[Ultralights]

sounds like a sacrificial annode type setup.   for metal to corrode, you need 3 things, 
an electrical current (flow path for electrons)
Oxygen
electrolite. (moisture in the air is enough to provide this)

remove any of the 3 above, and the metal wont corrode.
others include dissimilar metals in contact with each other(galvanic corrosion)

On my i30 I have a Couplertec     http://www.ebay.com.au/itm/Couplertec-Electronic-Rust-protection-Car-self-Fit-/190603480768?pt=AU_Car_Parts_Accessories&hash=item2c60da4ec0 

and on the Getz I have a Cat     http://www.ebay.com.au/itm/CAT-III-Electronic-Rust-Protection-4x4-Anti-Corrosion-/250867613218?pt=AU_Car_Parts_Accessories&hash=item3a68dffe22

Just looked at Couplertec while waiting for your response. Are you endorsing the product. 

[Paolo5]

Hi 847563,

When you say

Are you endorsing the product?

besides saying what I said in an earlier post about not having any rust in any of these cars I also said...

Not sure if they work but certainly can't hurt...

I know that there are some who would cry "SNAKEOIL!!!!!!" but I can only speak from the perspective of my own experience with the Couplertec unit which was taken from another car before it went into the Fuego. It is at least 10 years old and it still flashes....does it prevent rust? I like to think that it does.
I put an earlier version of the Cat unit into one of my ex-wive's cars around the same time. The car was in a small prang which left some exposed metal that never rusted in the few years that she had the car (which was longer than the marriage lasted....but that's another story)...

I just shelled-out several hundred $ for the new one which might demonstrate my faith in the product or my wishful thinking. Let's just say..

Not sure if they work but certainly can't hurt...

Maybe they should use your statement in their advertising.  "Your car will last longer than your marriage." Sorry to make light of your situation, hope you understand.

Sounds to me like they do help so I'll consider purchasing one soon. Thanks for providing details. 

[Paolo5]

Yeah....I can laugh about it.....now.


If it keeps going another couple of years I could change it to...

"Your car will last longer than 2 marriages"


Hell....with a claim like that, I'd buy one...

[Lakes]

  good one Paolo5.
well this guy i meet seemed to think they worked. if you want to find out mount it to a piece of clean bare metal leave it out in open see what happens, also have a twin to the piece with the gizmo mounted on it , with nothing on it to stand near by. see what happens to that can't hurt.
i think those roo shoo's are snake oil 

[Dazzler]

Yeah....I can laugh about it.....now.

If it keeps going another couple of years I could change it to...

"Your car will last longer than 2 marriages"

Gee  Don't say that 

They are dearer than I expected...

lakes

Yes, but I'd have to buy one to do that test. 

[jupitersj]

According to this guy, probably not. Nice long explanation..

[Dazzler]

He makes a fairly convincing arguement 

[Lakes]

I used to paint fish oil, inside my doors inside all body pannels & under floor mats. it must have worked just stunk like a fish markets for a month or so. i've never had a rusty car yet, might be because i don't keep cars a long time? & always keep them inside over night. never had a car stolen eather.

[Dazzler]

   I've used fish oil before but not anywhere inside the car... Under the floor mats
