HORHIZA 2-in-1 Rust Converter & Metal Primer — 155 oz Black, Water-Based Rust Inhibitor & Primer, Low-Odor

HORHIZA 2-in-1 Rust Converter & Metal Primer is a water-based, black rust inhibitor that chemically stabilizes rust and primes metal in a single, primer-free coat for long-term corrosion protection.

Built for both professionals and DIYers, this 155 oz formula converts existing rust into a sealed, paintable surface while acting as a durable primer for subsequent topcoats. The low-odor, water-based composition simplifies cleanup and minimizes toxic fumes, yet still provides abrasion, chemical and UV resistance. It works across steel, iron, aluminum and other metals, making it a versatile option for automotive restoration, outdoor fixtures, farm equipment and marine applications.

How does HORHIZA stop rust and prepare metal for painting?

The rust converter reacts with oxidized iron to form a stable, inert layer that bonds to the metal and prevents further corrosion. Simultaneously it deposits a priming film so you can paint without a separate primer, saving time and steps.

• Transforms rust into a protective, paintable surface
• Seals out moisture and salt to reduce future oxidation
• Creates a tightly bonded primed finish ready for topcoats
• Best applied after removing loose scale, then 2–3 thin coats

Is the formula safe and easy to use on DIY projects?

Yes — the water-based, low-odor formula is designed for safe handling and easy cleanup with water. It’s brush-applied and suitable for users who prefer simple prep and application without specialty equipment.

• Non-toxic, low odor, and water clean-up
• No separate primer needed: brush-on application
• Fast drying to touch and ready for recoat in about 24 hours
• Recommended: remove loose rust and debris before applying

What durability can I expect outdoors and in harsh environments?

HORHIZA offers long-lasting protection designed to withstand weathering, salt exposure and general wear. Its resistance to UV, chemicals and abrasion helps extend the life of metal components exposed to outdoor and industrial conditions.

• UV-resistant finish helps prevent sun-related degradation
• Chemical and abrasion resistance for demanding uses
• Seals against moisture and salt to slow future corrosion
• Ideal for marine, automotive, agricultural and fencing use

Which metals and projects is this product best for?

This converter-primer works on a wide range of ferrous and non-ferrous metals, making it a flexible choice for restoration and preventive maintenance jobs. It’s suitable whenever rust conversion plus a primed base coat are needed.

• Compatible with steel, iron, aluminum and similar metals
• Used on cars, trailers, machinery, tools and outdoor fixtures
• Appropriate for refurbishing and seasonal maintenance tasks
• Apply 2–3 thin coats for best sealing and coverage

Who is this for: HORHIZA 2-in-1 Rust Converter & Metal Primer suits homeowners, mechanics, contractors and restoration hobbyists who want a single, water-based product to neutralize rust and provide a primed surface quickly. If you need reduced prep time, low-odor application, and reliable weather-resistant protection across multiple metal types, this 155 oz solution delivers practical performance without specialty tools.
