3M 3513 Mar-Hyde One-Step Rust Converter Primer Sealer - 1 Quart

The 3M Mar-Hyde One-Step Rust Converter permanently converts rust into a hard, black primer sealer ready for topcoats through a chemical reaction. This professional-grade rust treatment eliminates the need for extensive scraping and sanding, saving valuable time in collision repair and restoration work.

Key Features:

• Chemically converts rust into a stable black primer sealer ready for topcoats
• Water-based latex formula with rust modifiers for easy application and cleanup
• Works on tightly bonded rust and flash-rusting on iron and steel surfaces
• Visual color change from white to purple to black indicates complete conversion
• Eliminates time-consuming sanding and priming steps
• Dries in 30 minutes
• Prevents new rust formation, protecting the integrity of finished surfaces
• Ready to accept additional primer or topcoat applications

After application, the treated surface transitions from white to purple and finally to a uniform black coating, making it easy to identify complete rust conversion. If white streaks or remaining rust are visible, simply apply an additional coat until fully sealed. Ideal for automotive refinishing, collision repair, and metal restoration projects on cars, trucks, motorcycles, and other vehicles.
