Ospho Qt Rust Treatment Inhibitor, Liquid, 1-qt. Jug

Ospho Rust Treatment Inhibitor is a liquid rust-inhibiting coating that chemically transforms iron oxide (rust) into iron phosphate, stopping corrosion at the source. This one-quart jug provides a practical solution for treating rusted steel, iron, cast iron, and alloy surfaces on automotive parts, machinery, tools, outdoor metal structures, and more. The treatment works without heavy scrubbing, saving time on repair and maintenance projects while protecting surrounding paint and finishes.

Once applied, Ospho leaves a protective anti-corrosion film that resists and retards future rust formation, giving you a sound, ready-to-coat surface for painting or clear-coating. Whether you're working in a professional shop or a personal garage, this rust converter delivers reliable results on ferrous metals across a wide range of applications.

Features and Benefits

• Chemical conversion: Converts rust (iron oxide) into stable iron phosphate, halting corrosion at the molecular level.
• Fast-acting: Works within minutes, ideal for quick turnarounds on automotive, industrial, and DIY repair jobs.
• Protective coating: Leaves a thin anti-corrosion film that inhibits re-rusting after treatment, extending equipment life.
• Paint-ready surface: Provides a sound base for primer and paint without extensive surface preparation.
• Metal-safe formula: Safe for steel, iron, cast iron, and alloy components without damaging underlying metal.
• Versatile application: Brush-on or spray-on use for automotive parts, machinery, tools, fences, and outdoor metal structures.
