Autosel 2-in-1 Rust Converter & Metal Primer — Black 70.5 oz, Water-Based, Heat & UV Resistant

Autosel 2-in-1 Rust Converter & Metal Primer is a water-based black rust reformer that converts active rust into a paintable, corrosion-resistant surface while acting as a built-in primer.

This heavy-duty formula combines rust conversion and priming in one step to simplify restoration and protection of metal parts. Designed for automotive, marine, trailer, and industrial use, the 70.5 oz container covers larger projects and offers a low-odor, low-VOC alternative to solvent-heavy coatings. It’s engineered to stop active corrosion, create a stable substrate for topcoats, and provide ongoing resistance to heat, UV, and chemicals.

How does this product stop rust and prepare metal for painting?

Instead of simply covering rust, the Autosel formula chemically transforms oxidized iron into a stable surface that bonds to paint. That treated surface then functions as a primer, reducing the need for separate sanding and priming steps on many surfaces. Application leaves a smooth, paintable finish ready for further coatings if you choose.

• Converts active rust into a stable, paintable layer
• Encapsulates and seals to block air and moisture
• Serves as an integrated primer for direct topcoat adhesion
• Works directly on rusty metal—sanding often unnecessary

What are the drying, curing, and application recommendations?

Autosel dries to the touch quickly and reaches full cure within a day under normal conditions. For best results, stir thoroughly, then apply 2–3 thin coats by brush or spray. Use the product within 72 hours after opening and allow proper ventilation during application.

• Touch dry in 2–4 hours; full cure about 24 hours
• Apply 2–3 thin coats; stir well before use
• Brush or spray application; minimal prep on flaky rust
• Use within 72 hours after opening for optimal performance

Is this coating durable in harsh conditions like heat, UV, and chemicals?

Yes — the formulation is made to withstand elevated temperatures, sun exposure, and common corrosive environments. It holds up as an undercoating, chassis or frame paint, and on marine hardware where resistance to heat and UV is important. While durable, topcoating with a compatible finish can extend color stability and abrasion resistance in severe environments.

• Heat resistant up to 350 °F (176 °C)
• UV-stable for outdoor exposure
• Resists common chemicals and industrial conditions
• Compatible with additional topcoats for enhanced protection

How safe and environmentally friendly is this rust treatment?

Autosel’s water-based formula is low-VOC and low-odor, making it suitable for both indoor and outdoor projects where reduced fumes are desirable. Cleanup requires only water, and the non-solvent base reduces flammability compared with solvent-heavy coatings. Follow local disposal rules for paints and containers.

• Water-based with under 1% VOC for lower emissions
• Low odor and non-toxic when used per label directions
• Easy water cleanup—no harsh solvents needed
• Safer storage and handling than many solvent primers

Who is this for: Professionals and DIYers who need a single-step solution to treat and prime rusty metal—especially on cars, trailers, marine hardware, frames, and industrial equipment. If you want a low-odor, water-based product that converts rust, primes the surface, and adds heat and UV resistance in a single 70.5 oz container, Autosel offers a straightforward, long-lasting option.
