does this rust prevention method have merit??
Sunday, July 13, 2008 10:15 PM
i saw this rust prevention unit and i thought maybe it might actually work. they use a ton of salt here and im doing every measure possible to keep my 91 cavy in good shape. right now the car is in excellent condition being a maryland car. if i could keep it that way for a long time, i would be happy.

I highly doubt it. The stealership i used to work for(my cuzin still does) put a unit like that on their cars. All they actually are, are a LED light in a black box.

sounds like the same theory someone had for stopping corrosion of lower units on boats a while ago... it didnt work there either.

Yeah i've seen similar at the stealership i work for, here there called anti corrosion modules. Aparently they only work on new cars but to be honest i can't really see how they work at all on any cars.

Scientifically, it's a sound idea... does it actually work? Not on a car... there's no path for the electrons to get back to ground.

This system has sacrificial anodes being used.. which is how it's done on boats and off-shore rigs, underground tanks, etc... compared to the power-only systems that, for example, are sold by Canadian Tire which are complete and utter garbage... without the zinc or whatever anodes to wear away, how would it work?? Look up "cathodic protection" to read more about it...

But unless you're somehow connected to a ground... won't work on car. On a boat in the ocean.. sure. On a steel tank in the ground.. sure. Not on a car.

+1. the systems i'm talking about actually used what they called an "electron gun" and a receiver. they didn't put zincs on it because it was supposed to work so well.. unfortunately, it never took off because seaweed/moss/grapes apparently LOVED what this thing was throwing, and they grew faster from the gun than they did normally. once the growth covered the little emitter holes on the gun, the receiver wasn't getting any more electrons, and the process was stopped. seems that just clamping a set of zincs to your stern drive was not only cheaper, but worked better anyway.

wait... what?

I read a lot about those systems... just electron emiitters, don't work on anything. Sacrificial anodes are proven, time over time.. always work. But combine them with electronic systems, and they're even better.
