Stop rust in its tracks! Our "Red" Rust Encapsulator has been formulated with SUPERIOR corrosion resistance to "hardware store rust paints"! Eastwood Rust Encapsulator has been tested by an independent lab to be one of the most effective rust-preventive products yet (tested to 500 hours in a salt-spray chamber). Red Rust Encapsulator is a great primer for floor pans and other underbody parts.

Also ideal for parts on project cars that have started to rust, but would be very difficult to replace or fabricate. For the absolute ultimate rust remedy, first brush or spray-on Eastwood Rust Converter, then prime with Rust Encapsulator. One 15-oz. aerosol covers about 10 sq. ft., and contains no isocyanates. Heat-resistant up to 400 degreesF. Made in the USA.
