Even though the corrosion protection system is completely effective in preventing rust, its primary mechanism reduces the speed of the electrochemical reactions which result in rust. If your vehicle has any surface damage or areas that are paint free, moisture and/or salt can result in the surface rusting, even if the rust-prevention device is working properly. It’s important that your vehicle is completely painted and free from surface damage for best results.

Prices for electronic rust prevention start at $395 installed.
