Rust is a costly exercise, and protection for a vehicle is best in-line with the old adage 'prevention is better than a cure'.
The concept of electronic rustproofing has been around for some time, with devices similar to Aussie Rust Guard being used for many years on bridges sitting in salt water and propellers on large vessels, to prevent them breaking down from constantly sitting in salt water.
The use of electronic rust units was originally made popular in mining and commercial applications, and the benefits were quickly recognised and applied to private vehicle use.

The unit is installed in the engine bay, securely attached to the vehicles fire wall with wiring connecting it to the vehicles battery.
While always connected to the battery, the draw is tiny, and will not drain any car battery in good-condition to the point where you would even notice it, let alone cause a problem. The unit will even shut itself down if it detects the battery has dropped below 11.3 volts (the usual level required to start a car). You can rest assured that your battery will suffer no ill-effects from the unit.
Out of sight, out of mind, but always protecting your vehicle from damaging rust and oxidation.
