HORHIZA Rust Converter & Metal Primer — 42 oz Black, 2-in-1 Water-Based Low-Odor Protective Coating

HORHIZA 2-in-1 Black Rust Converter & Metal Primer (42 oz) is a water-based coating that converts rust into a stable protective layer while acting as a ready-to-paint primer for metal surfaces.

This product blends rust-neutralizing chemistry with primer performance in a low-odor, water-cleanup formula designed for automotive, agricultural, marine, and general metal maintenance. It chemically bonds to flaky iron oxide, seals the surface, and creates a tough, adherent base coat that resists water, salt, UV and abrasion. Because it is formulated to be primer-free, it saves time on projects while providing long-term protection for metal parts exposed to the elements.

How does the rust conversion process work?

The HORHIZA formula reacts with unstable iron oxide to create a stable, black protective layer that prevents further corrosion. This chemical conversion stabilizes the rust and locks out moisture, improving adhesion for topcoats. Application requires removing loose scale and contaminants so the converter can penetrate and react effectively.

• Transforms rust into a tightly bonded, black protective coating
• Seals porous corrosion to block moisture and salts
• Prepares metal for direct painting without a separate primer
• Ideal for spot repairs and full-surface treatments

What surfaces and projects is this suitable for?

HORHIZA 2-in-1 is formulated for ferrous and many non-ferrous metals including steel, iron and aluminum, making it versatile for workshop and outdoor use. It performs well on automotive panels, trailers, fencing, farm equipment and boats when used according to instructions. For best results, apply to structurally sound metal with loose rust removed.

• Automotive body panels, frames, and undercarriage components
• Trailers, fences, gates, and metal outdoor furniture
• Farm machinery, implements, and industrial equipment
• Marine fittings and metal structures exposed to salt spray

How do I apply HORHIZA 2-in-1 for reliable results?

Surface prep is simple but important: wire-brush or sand to remove loose rust, oil and flaky paint, then clean the area before applying. Brush, roller or spray can be used; allow about 24 hours to fully cure between coats. Apply 2–3 thin coats rather than one thick coat to promote uniform conversion and adhesion.

• Remove loose rust, grease, and debris before applying
• Apply evenly with brush, roller, or low-pressure spray
• Allow approximately 24 hours drying time per coat at normal conditions
• Recommended 2–3 thin coats for durable protection and primer performance

What protection and maintenance can I expect after treatment?

Once cured, the treated surface provides a UV- and chemical-resistant base that reduces corrosion progression and stands up to abrasion. It forms a paint-ready surface, so you can leave it as a protective finish or topcoat with compatible paints for aesthetic or extra protective needs. Regular inspections and touch-ups will extend service life in harsh environments.

• Provides long-lasting moisture and salt resistance
• Resists UV, chemicals and mechanical wear
• Paintable surface for color or added protection
• Easy maintenance with periodic cleaning and touch-up

Who is this for: HORHIZA 2-in-1 Black Rust Converter & Metal Primer is aimed at DIYers, mechanics, fabricators and maintenance professionals who need a fast, low-odor, water-cleanup solution for arresting rust and priming metal in one step. It suits anyone restoring vehicles, protecting outdoor steelwork, maintaining agricultural tools, or preparing metal for repainting where time and simplicity matter. If you need a practical, long-lasting barrier against corrosion without multiple products or toxic cleanup, this delivers a balanced mix of performance and convenience.
