This 5 pack of 1 Gallon jugs will help you revitalize your steel surfaces. Utilizing powerful 21st Century technology, the sealant transforms rust into a slick polymer resin coating.

Power wash the surface before using and allow the surface to dry.

The coating can be painted or left clean after curing, ready for use. Never sweat over rust damage again with the Black Star Rust Converter.
