So I bought a car and the previous owner installed one of those

>electronic corrosion control

The what now?

>>16114150
it runs a weak current through the body and chassis and supposedly stops rust using science (???)

I don't really trust these things but it's already installed so I don't know what to do

Kek almighty that's some good snake oil

>>16114157
Those are called angots, and they work in water, or soil. Not open air

cathodic protection for your car

>>16114166
that was my understanding as well

so should I uninstall it and try to sell it to some retard on craigslist?

Is your car a boat?
If so, keep it in.
If your car isn't a boat, just take it out.

>>16114173
toss it

>>16114186
Thank you for making me laugh.

Rust only happens when water is present, and yet cars rust. Gee, its almost like moisture is present in the atmosphere in the forms of rain and humidity, I think I've even seen standing water in a street once....

Keep it OP. They only reduce rust, not eliminate- but they do work.

>All cathodic protection systems require an anode, a cathode, an electric circuit between the anode and cathode, and an electrolyte. Thus, cathodic protection will not work on structures exposed to air environments. The air is a poor electrolyte, and it prevents current from flowing from the anode to the cathode.

They don't do shit on a car. Pull that crap off and throw it in the trash. Oil undercoat it every fall if you want it to last.
