Anyone here know or tested this on their cars. Anyone think it could work? A guy over on the GTIR owners forum has one and i just wanted to see if anyone over here thinks its work trying?
This is a rough guide to what it is http://www.corrosionvci.com/Auto_Rust_Protection/
Looking at that page: it's complete, utter, total pseudoscientific knackers and a waste of money.
I do believe there is a key word in that sentance that suggests it probably won't work.has effectively controlled corrosion on underwater steel bridge supports
You get that impression just from the look of the site, you don't even have to start reading. What a load of bollocks.Originally Posted by randomnine
Just bolting some pieces of zinc to the body. E.g. wheel arches, would probably do the same thing. The zinc will "corrode" over time, preventing or reducing rust. It is sacrifical which is why zinc plated steel sheets last and plain steel sheets rust.
OK I have somewhat simplified what happens.
^ THIS!
Electronic rust control is a proven science.
Zinc plated steel stops rust as it's a total barrier first and foremost, and also is further along the galvonic table, so acts as sacrificial.
Bolting zinc to bits of car will only work if the cars is immersed in something conductive, air isn't so this will not really work
the idea behind zinc primer
ok lads i think you have taken the site to heart and i know it looks shit but its actually scientifically proven to work. ignore the look of the site its just there so you guys kind of understand what it is about. And i know all about zinc primers and sacrificial metals etc but i wanted to see your views on the electronic rust prevention. Not the shit site lol
Agreed, but as this country is so often wet and, in winter, the roads are salted this does provide some sort of protection.Zinc plated steel stops rust as it's a total barrier first and foremost, and also is further along the galvonic table, so acts as sacrificial.
Bolting zinc to bits of car will only work if the cars is immersed in something conductive, air isn't so this will not really work
Not that I would try it, though.
This only works when the whole thing you are protecting is connected and conductive, and is surrounded in conductive substance such as water.
I cannot see this working in air. I'd like to see the proof!
Of course it'll work, dont listen to the naysayers on here, you know it works, its even been scientifically proven, just buy the gear and get it set up. I believe you can also fit magnets around the fuel lines to help ionise the fuel, increasing performance and improving MPG, have you thought about getting some of those too?
It seems to be basically a system that uses the same principles used to protect steel rebar in concrete, electrochemical / cathodic protection. Any of the theory i know is based on steel sorrounded by concrete and needs the concrete for the system to work The rust is caused by the relitave acidity of portland cement and the water used to make cement reacting on the surface of the steel. By passing a current through the steel it becomes a cathode and the anodic reaction which causes the deteriation of the steel is isolated within the concrete protecting the steel. I know cathodic protection is used to extend the life of steel bridges too, but i have no idea how that works.
The theory works, but i stll wouldnt put faith in anything from that site tbh
^^^^^^^As above...
With any electrochemical or galvanic protection, the there must be a completed circuit in the presence of an electrolyte.
This is why it works underwater and underground / buried in concrete.
This is the similar principle to the magnesium sacricial anode fitted to hot water cylinders, the magnesium is destroyed first and the internal copper protected. However... The external surfaces of the pipework are free to chemically corrode or oxidise.
Oxidisation (Rust) is a different process from galvanic action and I'd love to see the evidence of this working on vehicles.
Proven science, yes in SOME applications... Doesn't work for all.
Same as a spanner won't undo a screw, it's not the job it was designed for.
sigh...
- It only works in water, because it prevents a kind of corrosion that only happens in water.
- The process requires a sacrificial metal.
- Even if it did work in air, it requires a constant current through the medium to the sacrificial metal. Because of the resistance of air, this would require an extremely high voltage. You'd have lightning arcing over your car. Sound safe?
- Your car's body is already negatively charged because that's your earth. Pump any kind of voltage into it and you'll **** up all your electrics.
Who did these tests? Where can we get the report?proven by independent laboratory tests
- "Galvanic differences" are only relevant to galvanic corrosion, which only happens when immersed in an electrolyte - like seawater. It doesn't happen in air.The signal produced by the Rustprotector is sent directly into the vehicle's body. From that point, a positive pulse is sent to all metal grounded to the vehicle body. This "pulse" works to equalizes the many small galvanic differences that exist in an auto body, effectively stabilizing the metal to guard against the damaging decay of metal perforation.
- They're chemical differences. A "positive pulse" won't "equalize" them. That's bullshit.
- Rust doesn't give a shit about "small galvanic differences". Rust is: iron/steel + oxygen + water = rust. Simple.
I think the problem is, he's almost saying that bridges have been protected by Electronic rust protection, in order to validate his product, but fails to say that the cathodic protection is by utilising a sacrificial anode and a completely different method to what he is describing.
as far as i know this does work, but not really on a car. it's to do with noble metals submerged in an electrolyte and a natural circuit flowing. the Sydney opera house has something like it. long and sort of it is something will corrode so better the zinc than all the iron holding the building up. i very much doubt it'll work on a car unless you left it in the sea!
Have you bought this kit yet? How much more evidence do you want, just get it and fit it.
Its on the internet.
It must be true !
