Corroseal Rust Converter & Metal Primer — 1 Gallon, Water-Based Pro-Grade Rust Treatment

Corroseal Rust Converter & Metal Primer is a water-based, pro-grade treatment that chemically turns rust into a stable magnetite layer while simultaneously priming metal for paint in a single application.

Corroseal offers an industrial-strength alternative to mechanical rust removal: instead of grinding or sandblasting, the formula converts iron oxide into a black, inert surface and leaves a high-quality latex primer behind. Designed for automotive, marine, household and industrial projects, this one-step solution reduces prep time, cleans up with soap and water, and helps protect metal surfaces from recurring corrosion when properly top-coated.

How does Corroseal stop rust without sandblasting?

Corroseal uses a chemical conversion process that reacts with iron oxide (rust) to form magnetite, a stable and non-reactive compound. That conversion stabilizes the degraded metal surface so it no longer flakes or actively oxidizes, removing the need for full mechanical removal in many cases.

• Converts rust to magnetite rather than simply masking it
• Chemical action penetrates scaled rust to form a solid black layer
• Reduces labor and equipment costs compared with sandblasting

What surfaces and projects is Corroseal best suited for?

Corroseal is formulated for steel and iron surfaces across automotive, marine, trailer, and general industrial uses. It works on rusty body panels, brackets, trailers, toolboxes, outdoor furniture and equipment where rust is present and a primed surface is required before painting.

• Use on ferrous metals (steel and iron) with visible rust
• Appropriate for boats, trucks, trailers, farm equipment and metal structures
• Ideal for spot repairs and larger surface restoration projects

How do you apply Corroseal for best results?

Application is straightforward: clean loose dirt and grease, then brush, roll or spray the product on at recommended wet film thickness. Apply a single coat at approximately 8–10 mils wet to achieve 200–250 sq ft per gallon coverage; allow adequate cure time before topcoating with compatible paints.

• Clean surface of oil, loose rust and contaminants first
• Brush, roll or airless-spray; maintain 8–10 mils wet film thickness
• Rinse tools with soap and water; allow conversion to cure before painting

What safety and cleanup benefits does Corroseal offer?

Corroseal is water-based, non-flammable and non-corrosive, so it’s safer to store and use than many solvent-based rust treatments. Cleanup is simple with soap and water, and standard personal protective equipment (gloves, eye protection) keeps application safe for DIYers and pros alike.

• Water-based formula — non-flammable and low VOC compared to solvent products
• Clears from brushes and equipment with soap and water
• Use basic PPE: gloves, eye protection, and good ventilation

Who is this for: Corroseal is made for professional contractors, restoration hobbyists, auto and marine owners, and maintenance crews who need an efficient, reliable way to stop active rust and prime metal in one step. If you want to reduce prep time, avoid heavy sandblasting, and create a paint-ready surface that resists further corrosion when properly finished, Corroseal is a practical choice for both small repairs and large-scale metal restoration projects.
