Electronic rust stopper?

SixPot

Has anyone ever tried such rust stopping electronic systems on their car? Do they work or are they a catch penny? I know the science behind them, but I mean do they actually work in the real world on cars?

Mmmmm...... No they don't work. http://corrosion-doctors.org/Car/car-electronic-rust.htm

I tried a system (similar to the one that you linked to) on my Rover P6, a car which is fond of rusting. I've had the car twenty eight years now, and the rust protector made not one iota of difference to the car's propensity to rust. I had the rust protector on the car for about ten years until recently. I suspect that it may even have accelerated the rusting process. Snake oil? Catch penny? Humbug? You bet!

I have one fitted to my 79 Datsun 200L, and it's pretty much rust free.
Though I don't think it's because of that unit!'

Is this the science behind it??.. I know its used in marine for a long time..
But I'd be sceptical if it would work on a car..
