ByronBayChris Posted 28March, 2016 Report Share Posted 28March, 2016 Anyone used this with any feedback ? Living so close to the water, rust is a concern from above. http://www.erps.com.au/ Link to comment Share on other sites More sharing options...
AAAC Posted 28March, 2016 Report Share Posted 28March, 2016 To my knowledge these devices do not have a scientific basis and it is unlikely that they work. Link to comment Share on other sites More sharing options...
CarreraG50 Posted 28March, 2016 Report Share Posted 28March, 2016 Not sure which particular one it was, but a friend who lives in Kingscliff had one fitted to his new Pajero. (doesn't take it on the beach, its used for towing)After a short while he noticed rust under the back seat (the device is in the engine bay) took it back to the installer only to be told on a vehicle this big????you need two, one at the front one at the rear!!!!!!! Kinda goes against the supposed science. However some of the surf life saving clubs have them and seem to endorse them. Link to comment Share on other sites More sharing options...
firstone Posted 28March, 2016 Report Share Posted 28March, 2016 I asked a surf club about their opinion once. The answer was, yeah probably but we only keep them 2 years anyway so who knows.Not much help.The theory. Corrosion, oxidation occurs when an unprotected metal is exposed to oxygen and moisture.

OZ930 Posted 28March, 2016 Report Share Posted 28March, 2016 Are you talking about the "polariser" that landed Peter Brock in trouble with GMH ?I found this on the Skeptics sitehttp://www.internationalskeptics.com/forums/showthread.php?t=66002 Link to comment Share on other sites More sharing options...
ByronBayChris Posted 28March, 2016 Author Report Share Posted 28March, 2016 I spoke with the life guards here and they believe that they are fitted to all their cars. Apparently trailers too....... I've asked to have a good look. Link to comment Share on other sites More sharing options...
werdna Posted 29March, 2016 Report Share Posted 29March, 2016 I've done some reading on these and asked a few people about these and they all seem to be pretty bogus unfortunately. As has been said above lifeguard utes and such are usually sold after 3 years. A few of my friends who are lifeguards have suggested never to purchase an ex-surf patrol car due to them rusting up.

Russ Posted 29March, 2016 Report Share Posted 29March, 2016 on another forum I frequent there was a great thread about these, snake oil.store your car in a garage and wash the salt off after going for a drive would be my approach Link to comment Share on other sites More sharing options...
ANF Posted 29March, 2016 Report Share Posted 29March, 2016 If it did work would not Porsche (and others) use this instead of costly galvanising and other methods? Link to comment Share on other sites More sharing options...
tazzieman Posted 29March, 2016 Report Share Posted 29March, 2016 Put a garden sprinkler underneath afterwards. That's what i did with L'cruisers I used near the sea.Was speaking to a guy at a party last Saturday and he said the salty air plays havoc with cars from warm and presumably humid states.If it's not galvanised there is a recipe for trouble. It's basic chemistry. Link to comment Share on other sites More sharing options...
Shady Speedway Posted 29March, 2016 Report Share Posted 29March, 2016 I've been fitting aftermarket automotive gear for more than 20 years.These work. Oil rigs use them. Steel wharfs have them.I wouldn't buy a cheap one. But I wouldn't buy the most expensive one either.Make sure the installer understands the system and you are confident with them. Clarify where and how they intend to install the unit before they drill holes and remove paint. Link to comment Share on other sites More sharing options...

tazzieman Posted 29March, 2016 Report Share Posted 29March, 2016 http://www.shannons.com.au/club/forum/general/electronic-rust-protection-voodoo-hogwash-or-fair-dinkum/You won't hear any success stories unless the poster was paid to provide it. Cathodic protection works perfectly on ships or steel bridges or metal pipes as long as they are earthed. The earthing provides the circuit completion required for Cathodic (electronic) protection to work and cars aren't earthed. Electronic Rust prevention devices have been banned in the US and Canada after being proven not to work. You will need much more than an earth strap to properly "earth" a car. Earth straps on cars are there to release the buildup of static charges only, so you don't get zapped opening the door or climbing out. Static charges have huge voltages and can leap the air gap and the momentary contact that an earth strap has with the ground. To really earth a car you need to attach it electrically to a metal rod plunged deep into the ground or have a metal-metal connection to some rail on the road....Ain't gunna happen. And then you still need the sacrificial anode. Placebo is too kind a description for this quackery.Oils ain't oils and boats ain't cars.My outboard has a nice fat zinc electrode to trap all the wayward electrons. My boat walks on water. Jesus! Probably the electrons acting like some sort of reverse magnet , or something. Link to comment Share on other sites More sharing options...
