Corroseal Rust Converter & Metal Primer 1 Gallon — Water-Based Rust Treatment & Primer for Cars, Boats, Trailers

Corroseal Rust Converter & Metal Primer is a one-step, water-based treatment that chemically converts active rust into a stable, paintable surface while simultaneously priming metal for topcoat application.

Designed for automotive, marine, household and industrial use, Corroseal replaces time-consuming mechanical rust removal by transforming iron oxide into magnetite and applying a latex metal primer in a single pass. The non-flammable, water-based formula cleans up with soap and water and is formulated to simplify surface preparation so you can paint sooner and protect metal longer.

How does Corroseal stop rust without sandblasting?

Corroseal uses a chemical conversion process that alters rust (iron oxide) into magnetite, a stable, black compound that bonds to the metal surface. This eliminates the need for full mechanical removal in many cases and creates a sound base for painting.

• Chemically converts rust to inert magnetite for improved adhesion
• Applies as a liquid — brush, roll or spray onto affected areas
• Often avoids extensive sandblasting or abrasive blasting steps

Will Corroseal act as a primer and what surfaces can I use it on?

Yes — the product leaves a latex metal primer film as it converts rust, creating a paint-ready finish in one operation. It’s formulated for ferrous metals and is suitable for cars, trucks, trailers, boats, structural steel and many other metal items.

• One-step conversion plus latex metal primer application
• Suitable for marine, automotive, household and industrial metals
• Compatible with conventional topcoats once fully cured

How do I apply Corroseal for best results and what coverage should I expect?

Apply Corroseal at 8–10 mils wet using a brush, roller or spray. Coverage is approximately 200–250 sq ft per gallon per coat; heavily pitted or porous surfaces will require additional material or touch-ups.

• Clean loose debris and loose scale before application
• Apply even coats at 8–10 mils wet for optimal conversion and primer film
• Allow adequate drying before topcoating; follow local conditions for cure times

Is Corroseal safe to use and how do I clean up afterward?

Corroseal is a water-based, non-flammable, non-corrosive formula that washes up with soap and water, making cleanup straightforward. Standard safety precautions like gloves and eye protection are recommended when handling any chemical product.

• Non-flammable and water-based for easier cleanup
• Use personal protective equipment to avoid skin or eye contact
• Dispose of unused material and containers per local regulations
