electronic rust control

[saturnsc2]

first of all i know how electronic rust control works like the systems that protect ship hulls. underground piping, bridges, ect. the devices for automobiles that operate on these same principles have been proven to not have any effect on preventing rust. as a matter of fact, one company who made a device called the rust evader was put out of business years ago because they made false claims for their product, yet in spite of all this, these two companys still make simillar units & say their units are "specially designed for an automobile". they promise up & down that their units called the "rusterminator" & "ruststop" really work. here is their websites: http://www.rusterminator.com/ & http://www.ruststopnorthamerica.com/ did anybody here ever buy these units? any comments? i still think it's b.s.....

well seeing as how rust is an electrical process, there is some merit behind this. However most rust occurs where dissimilar metals come into contact, such as around bolts and things. In these places it doesn't seem to me like this system would help all that much. For $180 there are alot of other things you can do to prevent rust. Although i don't think the system could hurt.

electronic rust control works by passing a current through a metal structure to electrically stabilize the metal & doing so, the metal resists corrosion. but the metal structure has to be submerged in a conductive fluid like water or moist soil as in underground piping. that's why it works on ship hulls & underground piping, or any buried metal structure. that's why i can't imagine this works on an autobody though as the body is not submerged. sounds like a scam to me--buyer beware. if anybody has any proof this works, i'll be so glad to hear it. go ahead--prove me wrong!

It wont work, every engineer I work with agree this wont work, Its a total scam

yeah--i thought so. it's a shame that people can just sell you anything even if it's a total hoax. i know that there was a company called the rust evader corporation that the federal trade commision put out of business because they made false claims about their unit that had absolutely no effect on corrosion. yet there is still companies now making those false claims about similar units. i can't understand why they don't shut down all of those crooks! i hate to get scammed by crooks. i bought that expensive 5-star shine that supposedly lasts 5 years & 150 washes & after a few weeks of rain, it is already washing off!

I believe that 5-star only works in Califorinia if you catch my drift. That stuff cant withstand being soaked for long periods of rain.
Also isnt there a way to clean rust by doing some electric method something like with baking soda electric current and water.

I still think that the system might have some merit considering the fact that proper electrical bonding between metal components reduces rust. thats a fact. it works on airplanes so why not cars.

it works on metal structures dipped in a conductive fluid & has for many years, but as i understand it, the metal structure that is being protected has to be submerged in an electrolyte because this completes the electrical circuit. without any electrolyte, there is no current flow over the metal & thus an incomplete circuit & no protection can occur. i never heard of this working on an airplane & i really never heard of any aircraft even needing such a device. aircraft are usually made of titanium, fiberglass, & aluminum, so such a device would not be needed.....

actually most aircraft skin is made of aluminum ( all big planes ) the FAA requires proper electrical bonding between surfaces that means that even if two pieces of metal ( especially dissimilar metals ) are directly bolted or rivited together you are required in most cases to connect the two with a bonding strap or bradded steel or some other metal depending upon the metal used in the bolts, rivets, and in the two pieces being connected. this is all so that there is free electrical ( electron ) flow between all surfaces on the aircraft. (If cars were made to last upwards of fifty and keep the original body pieces then they would have similar bonding.

so basically all i am saying is that there IS electrical flow between metal parts in cars so it seems logical that an electrical system would help to stop rust between anodes and cathodes.

In March 2001 someone by the name CS had posted the following"

"There has been no scientific evidence that you can successfully protection automobiles with cathodic protection unless it is submerged in water.


There have been two very good papers presented on the lack of scienific basis for using CP in this application:


Baboian, R., CATHODIC PROTECTION OF AUTOMOBILES, DOES IT WORK, NACE
Paper, Corrosion/87, 1987 and Materials Performance, Vol. 26,
no. 7, 1987.


Baboian, R., STATE OF THE ART IN AUTOMOBILE CATHODIC PROTECTION, PROCEEDINGS OF THE 5TH AUTOMOTIVE CORROSION AND PREVENTION CONFERENCE, SAE p-250, Society of Automotive Engineers, 1991 and SAE Transactions, Sept, 1992.


The Federal Trade Commission has taken a firm stance against firms that make claims of protecting cars by this technique."
