Corroseal Rust Converter & Metal Primer 1 Gallon — Water-Based, Single-Step Rust Inhibitor and Primer

Designed for automotive, marine, industrial and household metalwork, Corroseal uses a chemical conversion process to turn flaky iron oxide into magnetite, a more stable compound, and deposits a latex metal primer in the same application. This reduces labor compared with abrasive removal and provides a prepared surface ready for topcoat systems without harsh solvents. The product is water-based, non-flammable and cleans up with soap and water, making it practical for workshops, yards, and onboard maintenance.

How does Corroseal stop active rust without sandblasting?

Instead of only removing rust mechanically, Corroseal reacts with iron oxide to form magnetite, a dense, black, inert layer that stabilizes the surface. At the same time it lays down a latex primer film that improves adhesion for subsequent paints. This chemical approach reduces the need for extensive abrasive blasting and is faster on large or awkward parts.

• Converts iron oxide into magnetite through chemical reaction
• Applies as a single water-based coat that primes and stabilizes
• Reduces labor and protective equipment compared with blasting
• Prepares metal for conventional topcoats without aggressive solvents

What surfaces and environments is this rust inhibitor suitable for?

Corroseal works on ferrous metals across multiple settings—cars, trailers, boats, farm equipment, structural steel and household parts. It’s formulated for both indoor and outdoor use and is compatible with typical automotive and marine topcoats after drying. Avoid applying over heavy oils, loose scale or non-ferrous metals without proper preparation.

• Use on steel, iron and other ferrous metal surfaces
• Marine, automotive, industrial and general household applications
• Brush, roll or spray application options for different jobs
• Not intended for untreated aluminum or galvanized surfaces without testing

How do I apply Corroseal for best results and coverage?

Clean the surface of loose rust, dirt and oil, then apply Corroseal at the recommended wet film thickness. A single coat at 8–10 mils wet typically covers about 200–250 square feet per gallon; allow adequate drying before painting. Because it’s water-based, cleanup is straightforward with soap and water.

• Remove loose scale and contaminants before treatment
• Apply at 8–10 mils wet for 200–250 sq ft per gallon coverage
• Suitable for brush, roller or spray application methods
• Clean tools with soap and water—product is non-flammable

Who is this for? Corroseal is aimed at professionals and DIYers who need a reliable, time-saving solution to rusted metal without extensive surface removal. If you maintain vehicles, boats, trailers, agricultural equipment, structural metalwork or household metal fixtures and want a single-product treatment that stabilizes rust and primes for paint, this product offers an industrial-strength option that simplifies corrosion control and surface preparation.
