Autosel Rust Converter & Metal Primer — 35 oz Black, 2-in-1 Rust Remover with Heat & UV Resistance

Autosel 2-in-1 Rust Converter & Metal Primer is a ready-to-use black coating that chemically converts rust and forms a primer layer to halt further corrosion on metal surfaces.

Whether you’re restoring a trailer frame, treating farm equipment, or prepping a rusty car chassis, this 35 oz product combines a rust neutralizer and a primer in a single paintable formula. It penetrates and stabilizes flaky iron oxides, seals treated areas with a tough black coating, and is formulated for demanding outdoor exposures including heat, salt, and UV. Designed for professional and DIY use, it reduces the preparation steps while creating a durable surface ready for topcoat when fully cured.

How does Autosel stop rust without heavy grinding?

The formula is made to chemically transform rust into a stable protective layer rather than relying solely on mechanical removal. You should still remove loose scale and flaking material, but the product penetrates remaining rust and polymerizes into a black, adherent barrier.

• Ready-to-use; no mixing required.
• Penetrates and converts rust layers up to about 55 µm.
• Works as a rust encapsulator and foundation primer.
• Brush-on application simplifies tight areas and seams.

Will it hold up in sun, salt, or high heat?

Yes — the coating is engineered for outdoor and severe environments. It resists UV deterioration, road salt, coastal humidity, and sustained temperatures up to roughly 350°F, making it suitable for many automotive and marine surfaces.

• UV-resistant black finish helps prevent chalking.
• Formulated to resist corrosion from salt and moisture.
• Heat-tolerant, useful near engines and exhaust areas.
• Designed to withstand impact and chipping under normal conditions.

How long until I can topcoat or use the part?

The product forms a smooth black coating quickly and achieves full readiness for a topcoat after a curing window. Expect an initial skin in a couple of hours and full cure to accept additional paint in about 48 hours under normal conditions.

• Surface dries to touch in approximately 2 hours.
• Full cure and best adhesion for topcoats in ~48 hours.
• Drying times vary with ambient temperature and humidity.
• Sanding or scuffing may improve topcoat adhesion if needed.

What types of metal and projects is it suited for?

It is formulated for ferrous metals and works well on automotive frames, trailers, gates, farm equipment, and industrial tools. Use it where you want rust neutralization and a primer layer in one step, especially on items exposed to weather or road conditions.

• Automotive frames, chassis, and underbody repairs.
• Trailers, fences, agricultural machinery, and gate hardware.
• Marine fittings and coastal-exposed steel parts.
• General maintenance, shop repairs, and metal restoration tasks.

Who is this for? If you need a practical, professional-feel solution to stop active rust and create a paint-ready primer without extensive surface removal, Autosel’s 2-in-1 Rust Converter & Metal Primer is aimed at mechanics, fabricators, property owners, and home restorers. It works for anyone who wants a single-product workflow to stabilize corroded steel and prepare it for long-term protection and finishing — from weekend DIYers to maintenance crews in harsher climates.
