66yostagea Posted March 29, 2006 Share Posted March 29, 2006 as mentioned in "my mr3o replacement" my stagea has a thin film of underbody rust. has anyone tried ERP.would like to hear some feedback.

66yostagea Posted March 30, 2006 Author Share Posted March 30, 2006 excuse my ignorance but??????? i saw it at the brissie motor show. There are several firms that advertise it in the Yellow Pages. Endrust on the Gold Coast has a specialon it (electronic rust prevention) at present. has anyone any knowhow on this?

mike40sydney Posted March 30, 2006 Share Posted March 30, 2006 id never come across it before i spose a call to them would give us more info Link to comment https://www.sau.com.au/forums/topic/111669-electronic-rustprevention/#findComment-2061001 Share on other sites More sharing options...
timmmay Posted March 30, 2006 Share Posted March 30, 2006 my step dad has it on his hilux ute so i know exactally what you're talkin about! he lives about 1km if that to the ocean and over the last couple of years so far so good, no rust! mike: it's a device that sends electric pulses through the chassis of the car, and apparently it prevents rust from developing Link to comment https://www.sau.com.au/forums/topic/111669-electronic-rustprevention/#findComment-2061423 Share on other sites More sharing options...
Ska Posted April 6, 2006 Share Posted April 6, 2006 Yeah there is a company that supplies units to the gold coast lifsavers for thier equipment they run on the beach to prevent rust in them. Apparently they work by putting a special current through the metal and it keeps away rust...? Dont really know if they work or not?

Terminal Posted April 6, 2006 Share Posted April 6, 2006 I'm no chemist, but i seems to me it would be a simple redox reaction. similar to how the old lead acid batteries worked? i remember doing chemistry at uni and it had equations that were similar to that, but using lead and copper instead of iron (steel) Maybe something like Fe + O2 -> FeO2 + energy then the reversible reaction would be FeO2 (rust) + energy (our current) -> Fe (steel) + O2 (oxygen) therefore no rust develops this is from very limited chemistry, i'm sure it's more complex than that Link to comment https://www.sau.com.au/forums/topic/111669-electronic-rustprevention/#findComment-2075966 Share on other sites More sharing options...

3intheBack Posted April 6, 2006 Share Posted April 6, 2006 I know less then Terminal, But I believe he is right - rust is the result of a simple chemical reaction b/w the electrons in metal and the oxygen in the atmosphere. The presence of moisture speeds up the reaction as it is a good conductor. The whole electronic rust prevention idea works b/c it is based on sound scientific knowledge, but I read somewhere (or maybe heard it on Dr Karl) that you would need lots of electrodes all over the car to provide adequate protection as the area of influence is relatively small. Otherwise you would need a fairly large electical current running through the car body.

Terminal Posted April 6, 2006 Share Posted April 6, 2006 sounds like u know a fair bit, i sure dont remember anything from my old skool days einstein(sp?) in the house Hehe, nah i'm only a year out of my engineering degree, so i still have a bit of that 'learning' left in my head. give me a few years and i'll forget it.
