Stop rust in its tracks! Our Rust Encapsulator (White) has been reformulated with TWICE the corrosion resistance! It seals and stops rust and corrosion from spreading, but it performs even better than our original formula. Tested against well-known brands, the Eastwood Rust Encapsulator has proven to be superior in sunlight resistance, preventing rust creep, and overall durability Twice the corrosion resistance of our original formula for greater durability (tested to 500 hours in a salt-spray chamber) Epoxy-fortified for better adhesion and topcoat compatibility. Penetrates deeper to prevent rust from spreading or forming, even in hard-to-reach areas. Cures faster, and the low-VOC formula is acceptable in California. 15-oz. aerosol covers about 10 sq. ft.
