Rust-Oleum Professional Undercoating is an easy-to-use, black rubberized protective coating that provides corrosion protection from water, salt and other chemicals. This versatile formula can be sprayed or brushed. Professional Undercoating helps deaden sound and provides a barrier against rust on cars, vehicle undercarriages, wheel wells, trunks, boat trailers and other recreational vehicles. Not for use on surfaces that will come in direct contact with heat or high temperatures such as mufflers or exhaust components.

How to Apply Rubber Paint
Suitable Environmental Conditions
Use outdoors or in a well ventilated area such as an open garage. Use when temperature is at a minimum of 55Â°F (13Â°C) and humidity is below 85% to ensure proper drying. Avoid spray application in very windy and dusty conditions. Cover nearby objects to protect from overspray.
Bare Metal or Sound Rust Surfaces â€“ Surfaces must be free of dirt, dust, oil, grease and any contamination that may interfere with adhesion. For proper adhesion, sand the entire surface to be coated with 120-220 grit sandpaper and remove all sanding dust with a clean cloth. Protect and mask off all surrounding areas to prevent paint splatter. For best results, spot prime bare and rusted surfaces.
Previously painted/Coated Surfaces â€“ Use a wire brush to remove any loose or peeling paint or coatings. Sand the surface with 120-220 grit sandpaper. Thoroughly rinse the area with a mild detergent and water and then allow to dry before applying Rust-Oleum Professional Undercoating.
Rust-Oleum Professional Undercoating is ready to use. Do not thin or tint. Mix thoroughly to ensure that any settled pigment has been re-dispersed. For best appearance, apply using a high quality synthetic paint brush or synthetic roller. Do not use on surfaces that will be exposed to rain or moisture within 24 hours after application. For maximum durability, apply 2 coats.
