Mar-Hyde® ONE-STEP® RUST CONVERTER PRIMER SEALER chemically reacts to convert rust into a hard black primer sealer. Apply ONE-STEP® on rusted surfaces and rust is permanently converted and ready for primer and topcoat. ONE-STEP® RUST CONVERTER PRIMER SEALER is a water-based latex containing rust modifiers which is designed for application directly over tightly bonded rust on iron or steel. Also proven effective on new degreased or mild steel where flash-rusting has occurred. Shortly after application the rusted surface will change from white to purple to a stable black coating. A uniform black coating indicates the complete conversion of the rust; white streaks or remaining rust indicates that an additional coat is required.
