Rust guardian - Any one has or tried one?

[tesstickles]

Hello All,

As the title says; anyone tried and has one. http://www.rustguardian.co.uk; £204 inc Vat and P&P plus a couple of plates welded to the chassis (according to the answer to my enquiry). Seems like a small price to pay for long term protection and at least 'vastly' slowing down the rusting process.

Cheers

Kim

I think the chemistry is good in the test lab under very controlled conditions, as its a bit like revesing how a battery works, in so much the battery corrodes internally and provides a volatge as it does, so in theory you can reverse this principal to prevent the corrosion by applying a reverse voltage. BUT its a whole different ball game on a car chassis. To get the electron flow they refer to into the air you have to have a charge on the chassis at one side (say the negative side of the connection) and a postitive charge on the air itself, which is not so easy considering you dont have a permanent connection to the ground / surrounding air as you have 4 rubber tyres that insulate pretty well. Basically you would be better off with snake oil. (Well you can a least get a lot of good chassis wax for £200!)

Thank you for your e-mail After 17 years as the international distributor I can say without questionit would appear you do not understand the process of negative electrolysison vehicles I am sure you would agree Dr Donald Harrison the then Deputy Nuclear Physicsfor the UK Government would have a great deal more knowledge on the subjectthan you Dr Harrison tested CAT SYSTEM for two years on actual vehicles withexcellent results some 20 years agoSubsequently three other eminent scientists have tested the CAT in Canadaand Australia - all with success Suggest you read our website carefully - summaries of the above are there Your uniformed comments will be passed on to our UK distributor of longstanding Yours faithfully

Doesn't sound like a normal response to your posts! It would be interesting to see your email to them

Isn't he just saying you don't understand the process of negative electrolysis despite it being explained on their website and your comments were uninformed?

The system does work.

Well, it definitely works on fishing trawlers I have seen, most are fitted with cathodic protection.

Its a great system for submerged steel structures and steel hulled ships that are in constant contact with salt water.

More or less useless on a road car though.

To get the full effect just submerge your TVR in a salt water bath and watch the zinc sacrificial anode dissolve before your very eyes.

The key element the system needs to make it work is an electrolyte, in fact salt water is a perfect electrolyte.

But you need to submerge the protected ferrous metal in the electrolyte for it to be effective.

A road car chassis is subjected a changeable levels of moisture, damp then dry, then damp again, this is nowhere near the same as being submerged in an electrolyte.

Landcruisers have something similar - its called the aluminium diff lock actuators on the axles, they are like sacrificial anodes, in that they dissolve all by themselves, which is not handy when they are £400 to replace.

[blitzracing]

But this system does not use sacrificial anodes to liberate the necessary electrical charges, that’s the point. With a sacrificial metal, you set up a very small voltage flow between the zinc (i think ) block and the steel frame, and as the zinc "donates" this voltage charge as it corrodes, but the steel receives the charge so it does not. You could measure the odd volt or two if you wanted to between the metals. The system the OP is about talks about adding the charge to the steel plate, which is fair enough, but now on the other side of the steel is air, not zinc, so how do you set up a voltage flow between air and steel? If you make the voltages high enough you can get electrons to move to or from air as charged particles (Like your Van de graph generators) but you still need a reference point to ground or air to get a flow. I can quite believe that you could use the chassis as one connection , and an insulated steel plate near by to produce a local flow of charged particles, but its effect would be only between these two points, not the whole chassis. As I said in the lab yes, real world no. I certainly wont be hood winked by bluff from these guys. After all if it worked why bother zinc plating modern cars, when you could just put a few volts on the chassis, that would cost a whole lot less!

I couldn't be bothered to read the whole thing, I just assumed they must be using a sacrificial anode.

As described the system is truly nonsense, the science simply doesn't stack up.

The guy is clearly used to being on the defensive too ... speaks volumes

[taylormj4]

Yeah, I'll third that. I'm an electrical engineer (also with a Doctorate) and deal with cathodic protection now and again and would echo that there needs to be an electrolyte, which there isn't unless vehicle submerged as said before. Can't see what nuclear physics has to do with corossion anyhow ! WTF.
Incredible response from presumably a sales person too. Lol.

Cheers.
