I was at Lane Ford in Mandurah this morning signing up for my new car, and the guy started telling me about an electronic product called RustStopper.

Here's what the blurb sheet on it says;

"The RustStopper unit is 100% environmentally friendly, as this product is a third generation advanced technology electronic corrosion inhibitor. The module employss state of the art embedded computer controls to generate high speed pulsed current action to reduce iron loss or corrosion.

The RustStopper unit, when tested in accordance with ASTM-DM1654 test were shown to reduce the corrosion process by as much as 80%, effectively doubling your vehicles lifespan against rust and corrosion."


Anybody else heard of this?
Does it really work or is it a load of wank?

mmm sounds crap BUT the basic prinicple is called a Sacrificial annode bassicly the unit/annode has a lower potentional than the rest of the body and rusts first


ie Ships can put engine blocks on thier hulls so the engine block will rust away before the hull does

Isn’t corrosion and rust 2 different issues.
The idea comes initially from Porsche. But and there is a BIIIIIIIG BUT here.
Porsche uses a combination of different metals for their vehicle bodies which is not used by almost any other manufacturer.

If this was true and was working properly, EVERY manufacturer in Europe and other places where it rains and snows much more than Australia, where during their winters have to use sand and salt on the roads, would be having one of these units installed as OEM and for free on their vehicles.

But it is a good theory. :lol:

Rusting in an electrochemical reaction - the pulses basically sent a charge through the body of the car to stop the rusting reaction. Different to a sacrificial anode. (Maybe I did learn something in highschool chemistry after all)

Sounds like a bit of wank to me.
I'd just get a rust preventative coating. It will have a life time garauntee if you put it on from new and go back each year to have it inspected for under $100, nothing should happen to the body. If it does its covered.

As long as oxygen cant get in contact with bare metal you'll be fine.

exactly. nothing to do with sacrifical anodes which are in use on all outboard boat motors, and do work.
these electronic rust prevention systems have been around for a 10 years or so, and i have a friend who swears it works. Tho i'm a bit sceptical

hmm this is interesting it could well work but realy we wont know for around 15 years. how long are u gonna keep the car anyway? rust protection as far as im concerned is not a concern for a new car buyer in general.

I'll be keeping it for 10 years

My current EF I have had for 8 and I know it has had some rust in it for the past 5 years at least.

I was lucky enough to get the roof resprayed under warranty just before the Ford 5 year rust cover ran out - that would have been in early 2000

I do believe there is oxygen in water Frank, its what keeps the fishies alive. :lol: :lol:

I have CAT one of these, I bought it about 3-4 years ago to put on my 1980 LTD which had small patches of rust on it. Since I installed it the spread of rust has pretty much stopped, and no new rust has appeared on the car, which lives in my backyard, therefore I would say it works.

The guy I spoke to when I purchased it gauranteed that if the rust got significantly worse after installing it, that they would fix the rust in the car.

Since I sold the LTD, about 2 weeks ago, I have put the unit into my FBT.

If you are contemplating getting one of them DON'T buy it from Ford, mine cost about $450 shipped to Melbourne from Perth, with two transducers instead of one. I think ford wanted about $1100 for a similar device.

this product doesnt seem to be the same idea as a sacrificial anode, In a system of galvanic corrosion the most "active material" will migrate to the material that is the least active (this is why we run anti corrosion soloutions in our alloy headed cars) the migration accours through small electric currents (generated by the liquid and the differing materials) JUST like a battery (this is also why recargable batteries go bad) having an even more active material in the system (like magnesium in the case of an outboard motor) will mean that it will corrode and electroplate itself to the other metals.

My thoughts are that this system simply counteracts the electrical currents that cause the galvanic corrosion (by magnetism or what i dont know).

Rust and normal corrosion happens in a similar way, but in a much smaller system. Water gets trapped near the surface of the metal, oxygen in the water reacts with the metal (the water provides a medium for this to happen) bonding the oxygen atoms to the freed iron atoms creating "iron oxide" (ie RUST)

anyone looked at bridges around the world?

They have an electronic connection to provide cathodic protection to the concrete and reinforcing steel. I'd suggest this product works on the same theory.

Been around since the '50's

you sure? if anything having the parts electricly connected makes galvanic corrosion even worse, if anything youd want all the parts electricly connected in th event of a lightening strike.
