i didn't understand the iron oxide thing so had to watch it twice!

Hell your smarter than me, I had to watch it 3 times. When I thought I understood I watched it again just to make sure.
Been on the Boat too long!

You can miss some of the words, so you have to keep rewinding and replaying. Does Youtube have a slow motion play function?

I actually need to do some rust work now I've seen this. For the record it had nothing to do with the advert (total lie)!!!

Five Cougars thanks!

LOL. Sums it up for me, still laughing at this classic.

yeah I was reading the words thinking wow normally this type of information is boring, but now I am interested in how the salt rusts things...

Wha? I watched this a few times, where did that notion come from?

As seen on kedronownersgroup website. Food for thought.


OK, for the last three years of my "real" career I worked as a corrosion protection technician, or Rustologist as we prefer to call ourselves. I will not go deeply into the theory of these gadgets, I am simply going to say this: They do not work. Let's face it, if they did work every vehicle manufacturer would fit them as a standard item (to prevent claims for rust penetration.)
My last vehicle did not have one fitted, lived just 40 metres from the salt water for three years of the six that I owned the car, lived by the ocean for much of the rest of the six years and it had not one skerrick of rust when it was sold. The alloys used in steel making, along with the advanced coating compounds, negate the need for any further protection - even if it did work, which it doesn't.
Just one small bit of theory so that you can understand why they don't work. For cathodic protection to work, electrons must flow from the source (anode, electrical connection or whatever) to the steel being protected. For this to happen, the source has to be more negatively charged than the item to be protected. Because the body of the car is already connected, or grounded, to the negative terminal of your battery, the "capacitively connected" pad of so-called ERPS must be more negative than the negative of the battery! Not going to happen. Even if that could be done, for the "pad/s" to create a field to protect the entire body of the vehicle you would have to immerse the vehicle in conductive soil or a conductive solution. Hardly practical.
I was at a conference of the Australian Corrosion Association, where the keynote speaker chose to explain the theory of ERPS to the attending corrosion engineers. He filled two white boards with formulae, drawings and blurb. At the conclusion of his piece he simply wrote in huge capital letters "THEY DON'T WORK, THEY CAN'T WORK." This guy is right up there on the pecking order of Corrosion Engineers, so I have absolutely no reason to doubt him.
I wouldn't be parting with my hard-earned for one of these bogus systems.
Cheers
