Encore Coatings ROX-1-B 1 gal RustOx Advanced Rust Protection Black is perhaps the most versatile metal coating on the market. With an ability to adhere to virtually every metal surface, RustOx creates a tough, durable coating that lasts for years. When applied on rusted metal, RustOx suffocates the surface rust and prevents rust bleed-through. Surface prep is simple. Just remove loose rust scale or loose coating, and wipe down. If necessary, remove surface oils with MEK. RustOx dries quickly and provides years of protection against further degradation. Approved for inland and salt-water environments. Recommended for steel, aluminum, and galvanized surfaces.
