The Magnetic Paint and Shellac Co UCP99-01 Chassis and Underbody Coating is a high solids, VOC compliant, single component formula designed to stop automotive and truck corrosion without the need for primers or topcoats. The coating cures by reacting with atmospheric moisture, forming a durable, non porous finish. It bonds directly to blasted or rusty metal surfaces, creating a rock hard yet flexible glaze like coating that resists cracking, chipping, flaking, and peeling. Designed for chassis and underbody applications, this coating supports long term corrosion protection in demanding service environments.
