Mopar MasterShield Rust Inhibitor

Protect your Ram 1500 from the inside out with the Mopar MasterShield Rust Inhibitor — a wax-based corrosion protection formula engineered to guard doors and exterior body panels against rust-through for the long haul.

Fogging Spray Application: Utilizes a fogging spray method that penetrates deep into hard-to-reach cracks and crevices — delivering maximum inside-out corrosion protection where traditional coatings simply cannot reach.

Wax-Based Formula: The wax-base chemistry bonds to interior metal surfaces on doors and exterior body side panels — creating a durable barrier that resists moisture and the conditions that cause rust-through.

Comprehensive Coverage: Specifically targets doors and exterior body side panels — the areas most vulnerable to trapped moisture and long-term corrosion damage on your Ram 1500.

Bottle Size & Quantity: Each bottle contains 31 oz of rust inhibitor formula — with a minimum sell quantity of 12 bottles per order for fleet, dealer, and volume protection applications.

New Vehicle Warranty Documentation: Includes one new vehicle warranty book with each bottle — ensuring proper documentation is on hand for dealer-applied corrosion protection records.

Mopar® Engineering: Formulated and backed by Mopar to meet the corrosion protection standards of Ram 1500 factory specifications — delivering confidence-inspiring, OEM-grade durability.

Part 82212074AB is the smart upgrade for Ram 1500 owners who want factory-grade rust protection that reaches where it matters most — safeguarding doors and body panels from the inside out, preserving structural integrity, and extending the long-term life of their truck.
