Easy to Apply, Easy to UseMar-Hyde™ One-Step Rust Converter Primer Sealer combines powerful rust modifiers with an easy-to-apply water-based latex that brushes on smoothly and cleans up quickly. Shortly after application, the rusted surface changes from white to purple and finally to a stable black coating. A uniform black coating indicates the complete conversion of the rust; if any white streaks or actual rust remain, simply apply an additional coat of rust converter until the surface is completely sealed.Permanent Rust ConversionRust is not simply dissolved or covered up during this process. It is chemically converted into a hard, black primer sealer that readily accepts additional primer or topcoats. Instead of scraping and sanding, technicians can lightly brush the surface and let Mar-Hyde™ One-Step convert rust to primer sealer. It converts tightly bonded rust on iron or steel, and flash-rusting on new degreased or mild steel. It also prevents new rust from forming, ensuring that primers and topcoats will remain bonded for smooth, long-lasting finishes in auto body repair.Better Science for Better Collision Repair OperationsMar-Hyde™ One-Step Rust Converter Primer Sealer is a true step forward for collision repair professionals.
