A high-tech formula halts residual rust in its tracks and converts it into a black protective polymeric coating that eliminates the need for sanding. The converted protective coating is a suitable primer, compatible with most top coats. Additionally, the protective coating will seal the surface against moisture to prevent future rust growth. Simply remove loose rust with a wire brush, then apply Rust Converter / Sealer. Allow to dry, then top coat it with a quality coating. Single component, no more mixing. Paintable.
Preparation:
Degrease and remove loose scale and paint with a wire brush. Rinse with water to remove salt and chemicals and allow to dry. It is not necessary to remove all traces of rust.
