Eletronic rust prevention

Hi Carl

Tell him to make sure he washes thoroughly including underneath & polishes a soon as possible after every trip.
I am sure he like many who have bought a EPRS will find little rust

Hi Royce

My prado is 10 years old, black in colour and looks brand new. Yes it has one fitted and no I dont:

"feel silly if it was just because they kept thier vehicle clean"

because my poor car has only had about 6 washes since early 2006 when I suffered a spinal injury that required me to undergo spinal surgery a year ago. It also doesnt have any rust despite having spent time 4wding on the beach.

My research suggests those that knock them never had one or had one fitted correctly, OR had the wrong type fitted. Yes there is a wrong type, one that is for objects permanently in water - suggest you look into it and then use your new found knowledge to educate the world (and yourself).

Now to start the tyre debate: are Coopers any good HAHAHA

To CARLJ - get the correct type as suggested in one of the other replies - ERPS.

"research"??

I just 'looked into it" again. The only people supporting it are people who sell or are convinced to buy. Other more objective reports are no where near as supportive.

Hi
I was a little tongue in cheek with my earlier post
But The FACTS are they do not & can not work on a vehicle
Any one who has a basic understanding of impressed voltage corrosion systems [ as used in industry etc] will understand
The principles are correct, but it simply cannot be applied to a vehicle by means of wires to parts of the body or small plates attached to various parts'

can I ask you, as some one who has no basic understanding of impressed voltage corrosion systems, to elaborate ..... ??

Hi Mainy
I used the term of impressed voltage to make it easier to understand.
Most corrosion protections use consumable anodes of zinc, magnesium lor even aluminium .
The surface being protected is the cathode
The system is called "cathodic protection"
This is the system used in hot water systems ,it is also used to protect underground metals & metals in water[salt & fresh]

By impressed voltage I mean the system were you actually apply a carefully controlled voltage resulting a small current flow via a non consumable material [ stainless steel can be used in many cases] to perform similar to consumable anodes .It is still referred as "cathodic protection"
In some situations .[very corrosive liquids in steel tanks] it requires the tank becoming the anode & the impressed voltage system is use it is then referred as "anodic protection"

All these systems require for there to be a conducting material {Electrolyte]between anode & cathode for the curreent to flow INTO/OUT OF THE SURFACE of the material to be protected.

My Parents have lived on Bribie for 22 years. The have had the same old Subaru for that period. It is completely rust free. It does not have a electronic rust preventer in it.

Hi Dave

Yes even with impressed voltage the polarity must be correct..
If you look @your vehicle earth system just think of all the diferent currents flowing along that metal . Why would adding a little more make any differance.
But the real point is current flowing along the metal does not protect , it has to flow into the surface.
If you put a plate over an area & apply a controlled voltage /current the area UNDER the plate will be protected , but that is all.
