LISRUX Rust Converter & Metal Primer — 34 fl oz Black, 4-in-1 Water-Based, Heat & UV Resistant

LISRUX 4-in-1 Rust Converter & Metal Primer is a water-based, industrial-grade rust reformer and primer that converts rust, seals metal, and provides heat- and UV-resistant black protection.

Engineered for automotive, marine, industrial and home use, this ready-to-use 34 fl oz coating neutralizes active rust, blocks oxygen and moisture, and creates a durable primer layer suitable for topcoat or standalone protection. The formula is low-VOC and cleans up with water, while offering heat resistance up to 350°F and long-term corrosion control when applied per instructions.

How does this product stop rust and protect metal surfaces?

The LISRUX formula chemically converts iron oxide into a stable, inert layer that isolates the metal from oxygen and moisture. Once cured, the coating forms a sealed, black primer film that prevents further oxidation and provides a consistent base for painting.

• Active rust is converted to a non-reactive coating.
• Seals out water, salts and corrosive contaminants.
• Creates an adherent primer layer for finishing coats.

What surfaces and environments is this rust inhibitor suitable for?

This product is formulated for a wide range of ferrous metal applications: automotive panels, chassis parts, machinery, marine fittings, structural steel and construction equipment. Its heat tolerance and UV-resistant finish make it useful in engine compartments, exhaust-adjacent parts and outdoor installations.

• Automotive frames, fenders and underbodies.
• Industrial machinery, welds and structural steel.
• Marine hardware and outdoor metal fixtures.

How should I apply LISRUX rust converter for best results?

Prepare the metal by removing loose scale, oil and heavy contaminants, then ensure the surface is dry before application. Apply thin, even brush coats, allowing about 24 hours between layers; at least two coats are recommended. Avoid painting in rainy or highly humid conditions and keep the coating dry for seven days after completion for optimal cure.

• Remove loose rust, grease and debris first.
• Brush on thin layers; wait 24 hours between coats.
• Avoid exposure to water or humidity for 7 days post-application.

What practical benefits and maintenance features does this product offer?

Besides converting and stopping rust, the product simplifies cleanup and reduces environmental impact thanks to its water-based, low-VOC composition. Tools rinse clean with water, and the cured coating gives UV resistance for longer-lasting appearance and protection.

• Water-based formula with less than 1% VOCs for safer handling.
• Easy tool cleanup with water—no harsh solvents required.
• Heat resistance up to 350°F and UV-resistant finish.

Who is this product for? LISRUX 4-in-1 Rust Converter & Metal Primer is designed for DIYers, mechanics, fleet managers, fabricators and facility maintenance teams who need a dependable, industrial-strength rust treatment that doubles as a primer. If you work with ferrous metal exposed to weather, road salts, heat or corrosive environments and want a low-VOC, easy-clean solution that creates a paintable base, this product is a practical choice.
