Saw a commercial on TV for a device that protects a car from rust. I think it might be too early to ask if this thing works so how about some opinions?

theres a thread floating around here about this product actually... its got a sound idea (from what i remember) but no one wants to spend 200 without someone else trying it first...

basically it sends an electric current through the body of your car, and all that ends up rusting is a sacrifiacial piece of metal... that ocasionally needs replacing... so go ahead and try it... a quick search couldn't find the thread...

Yes it really works... infact manufacturers could of stopped rust a long long time ago but they don't! you know why? cause it makes US the consumers buy more vehicles!

All it is, is u hook up a positive and negative to the body of ur car and wala... no rust forever since rust only bonds to negative molecules and if u have a constant current goin through it doesn't like it. Hard to explain and I hope I explained it correctly but that's the broad idea.

So then does anybody know if a car has started rusting a bit already, would it stop the rust from growing?

Learned about this in school...damn i actually learned something but yes it works. They use this method on pipelines in the oilfield industry. Also the metal they use acts as a sacrificial anode so basically the metal that gets eaten away is weaker than the metal on the body of the vehicle. Zinc works good...I would need to pull out my old table of elements but it depends on how many valence electrons there are on the outside of the nucleus in the atom of that specific element.

I was considering this, but from what I've read in other threads on the net, it wouldn't really work too well. This would be due to the car not being grounded to earth because of the tires (no conductive medium unless the air is really humid). (I thought there was no sacrificial anode but I guess it comes with another metal to attach to the frame)

I've seen 2 cars with these (not the crappy tire ones though). Both were installed brand new, both have developed rust.

its the same type of thing they use to make sure underground pipes dont rust up...technically works but im sure there are some exceptions...every car body is different and i doubt it'll work the same for for all of them

They've had this sort of thing since the 60's advertised. From people I've talked to in the industry, it works well in indudtrial settings. Water pipes, towers, pipelines, etc are the targets. The system needs a continuous connection and that the subject (pipe) be wet.

In automotive use, it is a bit less effective. The sacrificial anode is usually something aluminum which tends to react before the steel. The snag is that the parts of a car are not all linked and it is not always wet

It's a similar idea to galvanizing parts or full chassis like Porsche and others. The zinc coating on a galvanized part is sacrificial, the coating being eaten before any rust appears on the part. Well, that's the theory.
