Rust-Oleum Professional Undercoating is a black rubberized protective coating designed to shield the undercarriage of cars, trucks, trailers, and other recreational vehicles from rust and corrosion. This aerosol spray creates a durable barrier that protects bare or primed metal, including underbodies and wheel wells, from water, salt, road chemicals, and moisture that cause rust damage. The rubberized formula also helps deaden sound, reducing road noise while providing protection for your vehicle's underside.
The coating is quick-drying and paintable, making it ideal for both preventive maintenance and repair applications. Whether you're protecting a new vehicle before winter or restoring the undercarriage of an older model, this professional-grade undercoat offers reliable corrosion defense in a convenient, easy-to-apply spray format.

- Rubberized Black Coating: A flexible rubberized finish that adheres to bare or primed metal surfaces.

- Paintable Finish: The coating can be painted over if needed for additional customization or color matching.

Covers area pretty well, seems to hold up well. Nice finish.
Works really nice
I prefer this stuff over the Permatex. Goes on really nice. Would definitely recommend
Great protection
I painted my old army trailer, after wire brushing the old paint off, and this paint really holds and should protect for a long time.
