Eastwood's Rubberized Rust Encapsulator is the flexible version of our high-performance Rust Encapsulator coating that applies directly over rust or bare metal to provide long-term corrosion protection.

Unlike off-the-shelf under coatings, Rubberized Rust Encapsulator can be applied directly over rust and without the "bubbling" that creates air pockets thus trapping rust. Since its engineered with high-tech flex agents, its pliable finish protects surfaces from abrasions, road hazards and deadens sound. So durable it exceeded 1,000 hours of salt spray chamber testing, this surpasses the standards for a 2-component catalyzed coating! Simply apply directly over rust or bare metal; no need to topcoat. Remains flexible and durable. Satin black finish.


Use a wire brush to remove loose rust, scale and paint, and remove dust, grease and oil deposits. Feather surrounding paint with 220-grit sandpaper. Shake can for at least 2 minutes once the mixing ball starts to rattle. Hold the Rubberized Rust Encapsulator can 10"-12" above surface as you spray. A single coat dries to the touch in 20 minutes, and is thoroughly dry in 3-4 hours at 68℉. For greater durability, a second coat can be applied 1 hour after the first. Allow 6-8 hours after the last coat before applying topcoat (no need to topcoat, unless desired). Quart may be brushed on or applied with an undercoating gun
