RUST CONVERTER 1. Surface Preparation: Before applying the rust converter, the rusty surface should be cleaned and free of loose rust, grease, oil, and other contaminants. This can be done using a wire brush, sandpaper, or a degreaser. 2. Application: The rust converter is applied to the rusty surface using a brush, roller, or spray gun. It is important to follow the manufacturer's instructions regarding application methods, coverage, and drying times. 3. Conversion: Once applied, the rust converter reacts with the rust, forming a black or dark-colored compound called iron tannate or iron phosphate. This compound stabilizes the rust and provides a protective barrier against further corrosion.
