Autosel Rust Converter & Metal Primer 35 oz — Black, Heat-Resistant UV-Stable Protective Coating

Autosel 2-in-1 Rust Converter & Metal Primer is a ready-to-use black coating that chemically converts rust and creates a durable primer layer to stop further corrosion.

This dual-action formula combines rust conversion chemistry with a primer binder so you can treat rusty metal without sanding back to bare steel. Formulated for automotive, trailer, farm, and industrial use, the product penetrates flaky rust, seals surfaces, and forms a tough protective black coating that accepts topcoat paint. It’s heat resistant to 350°F and engineered to withstand salt, UV exposure, and humid or coastal environments.

How quickly does Autosel stop rust and how does it work?

The product neutralizes active corrosion by chemically transforming iron oxides into a stable, paintable layer. You’ll see visible darkening as the rust converts and a continuous film forms within a few hours; full cure occurs in about 48 hours to accept a topcoat.

• Penetrates and converts rust up to heavy layers (approx. 55 µm).
• Forms a binder-rich primer that blocks oxygen and moisture.
• Creates a black protective surface ready for overpainting in 48 hours.

What surfaces and projects is this rust reformer best for?

Autosel is designed for ferrous metals across automotive, agricultural, marine, and structural applications. It works well on frames, chassis, trailers, fences, gates, tools, and industrial machinery where long-term corrosion resistance is needed before finishing.

• Automotive frames, truck chassis, and trailer underbodies.
• Farm equipment, metal gates, and outdoor structures in salt-prone areas.
• Marine fittings, industrial equipment, and maintenance touch-ups.

How do I apply this rust converter and what surface prep is required?

Surface prep is simple: remove loose scale, flaking paint, and heavy debris, then brush or wipe clean. The product is ready to use straight from the container—apply by brush or roller, allow the coating to develop for a few hours, and let it fully cure for topcoating or service.

• Remove loose rust and contaminants; no need to grind to bare metal in many cases.
• Brush, roller, or low-pressure spray application is possible.
• Forms a smooth black coating in about 2 hours; full cure in 48 hours for topcoat.

Will this coating hold up to weather, heat, and road conditions?

Yes—Autosel is formulated for extreme conditions and resists chipping, high heat up to 350°F, UV exposure, humidity, and road salt. It acts as both a corrosion inhibitor and a primer layer, extending the life of metal components in demanding environments without immediate repainting.

• Heat-resistant up to 350°F for engine bays and hot components.
• UV- and salt-resistant for coastal and winter road use.
• Impact- and chip-resistant finish suitable for exterior metalwork.

Who is this for: Autosel 2-in-1 Rust Converter & Metal Primer suits professionals and DIYers who need a fast, reliable way to halt rust and prep metal for paint without full media blasting or intensive surface stripping. It’s ideal for vehicle restorers, fleet maintenance, farm mechanics, contractors, and homeowners tackling outdoor metal repairs seeking a long-lasting, heat- and weather-resistant primer that simplifies rust repair and finish painting.
