Rubberized Undercoating – Protective Spray for Automotive Rust & Sound Insulation

Rubberized Undercoating is a durable, spray-on protective coating formulated to guard vehicle underbodies against rust, corrosion, moisture, and abrasion. Its flexible, rubberized texture creates a tough barrier that also helps reduce road noise and vibration, making it perfect for wheel wells, floor pans, undercarriages, and other exposed metal surfaces. This easy-to-apply formula adheres well to bare or primed metal and dries to a non-drip, black finish that resists chipping and peeling. Ideal for automotive professionals, restorers, and DIYers, Rubberized Undercoating enhances both protection and comfort while maintaining the vehicle’s structural integrity over time.
