Electronic Rust Protection Module for car, Truck, SUV, ATV, Boat or Trailer | Anti Corrosion Module | Electronic Rust Control Device|

Looks cheap just hope it works.

It includes all you need to fit it.Very well packaged.I have used this type of rust prevention since my second car in 1989.It works.I have used it on forklifts working in corrosive environments, with very good results.It will drain the battery if the vehicle is not being used for long periods, ie 1 month.

I bought this with reasonable expectations. When I opened the package and read the directions, my first thought was, “Wait, what? This doesn’t do anything.” There are two wires to connect directly to your battery. Then there is a single additional wire to connect to the body of the car. So, how is this supposed to work? There is no way to complete the electrical circuit. It’s the same as having your car battery connected. This is a snake oil type of product. Save your money.

Minnesota nice will corrode humans let alone metal. Worth tying

With water being at a relatively constant voltage, a boat hull can be negatively charged with respect to water.Not so with the atmosphere, (where car rust happens) which has wildly changing electrical charges all around the car. One example: Everybody's felt a static electric charge in their life. That's thousands of volts, positive and negative. Tires on the road can do more. So whomever tells you that a 12 volt system can overcome these thousands of volts is selling false hope. Except maybe for a few millimeters surrounding the pads where the atmosphere might get charged - but even that's a stretch.So unless you plan to submerge your car in water, this product won't - can't help with rust.BTW - the review that says this can be dangerous based solely on current numbers doesn't understand electricity very well. It's not dangerous. But that's a different discussion.

Adding electricity to the frame or body of your vehicle (places it can rust) is hazardous and potentially deadly. It only takes 0.2 amps of power to kill a human being at most. This A.) does not work, B.) if it does what it says this could be harmful to you. You either are buying false advertising or a product that will harm you.
