Rust & Corrosion Protection

How this plan helps you?

Before you even turn the key for the first time, the metal used to manufacture your new car or truck has started transforming - has started to set in. It happens when metal, oxygen and water combine to create an electrochemical reaction. If you remove or control one of the three elements in that simple rust formula, you can prevent corrosion. And that’s exactly what Diamond Kote’s Rust & Corrosion Protection does.

Rust & Corrosion Protection


Enjoy the peace-of-mind that comes with knowing every panel on your vehicle covered by Diamond Kote is protected and will be repaired should any unexpected damage occur. We offer full body panel corrosion protection, undercarriage corrosion protection and surface rust protection to keep your vehicle looking new.

Plan details


The new Diamond Kote Corrosion Protection Unit (CPU) is a revolutionary wireless automotive corrosion protection device that uses the vehicle’s electronic diagnostic system to protect your investment. The CPU detects and protects all weak spots on every metal component of a vehicle’s metal body – outside and in – so nothing gets missed. Everything is monitored so everything stays protected.

The DK9000 Module sends a positively charged, low voltage current throughout the metal of your vehicle to cancel the negative free-electrons, which are naturally present and continually causing rust. Then the module’s sacrificial anodes, which possess a naturally higher positive charge than your vehicle’s body, deal with any corrosion before it starts to set in.
