Undercoating Rubberized Spray

This Rust-Oleum undercoating applies evenly and creates a thick protective layer that adheres well to metal surfaces. The texture is uniform and dries to a firm finish that helps reduce moisture exposure. It sprays smoothly and does not run when applied in controlled passes. Once cured the coating feels durable and provides good resistance against road debris and salt. It is effective for covering existing small surface rust and helps prevent further spread when applied properly. The cans spray consistently across the entire set so there is no variation in finish between applications. For anyone looking to protect the underside of a vehicle or metal components this product offers reliable performance and long lasting protection.

Amazing product. I already used it. It works beautifully and it arrived on time and ran on my doorstep. Thank you Amazon.

Bought it to use under RV. After thoroughly cleaning space to coat, product sticks great. Goes on evenly. I recommend at least two(2) coats. Shake well and shake between spraying. Really good product.

Does the job. Used to undercoat new fender. Big advantage here was lower price on amazon.

Worked great. Used this for my horse trailer undercarriage and steel frame both inside the tack room and horse hauling area. I would buy a spray can handle and not try to apply it just using the can as is though.

This stuff is awesome unlike some others this on sticks like glue

Good product covers well

Easy to use on my 2026 F150 without wheels well inserts with blackout package it looks awesome when wheel wells are sprayed

Best for applying under car body. Well it takes around three days for complete dry and strong coating.

Fast delivery
