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

Autosel 2-in-1 Rust Converter & Metal Primer is a water-based black coating that chemically transforms surface rust into a stable, paintable layer while also serving as a primer and protective topcoat.

Whether you’re restoring a car frame, protecting a trailer, or maintaining marine hardware, this concentrated 70.5 oz formula simplifies corrosion repair by combining rust conversion and priming into a single application. The non-solvent, low-VOC composition makes it suitable for indoor or outdoor use, and its cured film resists heat, UV exposure, and common chemicals common in automotive and industrial environments.

How does this product stop existing rust and make the surface ready for paint?

The formula reacts with iron oxides to neutralize loose rust and bond to the remaining material, creating a stable black surface you can topcoat or leave as a protective finish. Surface preparation is minimal compared with traditional systems — you remove flaky rust, then apply the product to convert what remains.

• Acts chemically on iron oxides to form a paintable substrate
• Seals the metal to block oxygen and moisture
• Requires removal of loose scale but no full abrasive blasting in many cases
• Dries to touch in 2–4 hours and cures within 24 hours

Can I apply it directly on vehicle frames, trailers, or boat fittings?

Yes — this coating is designed for direct-to-metal use across automotive, trailer, and marine applications. It adheres to prepared rusty metal and provides a durable barrier that stands up to common service conditions found under vehicles and around watercraft.

• Suitable for chassis, frame, and underbody areas
• Resists heat up to 350 °F (176 °C), helpful near engines or exhaust
• UV and chemical-resistant for outdoor exposure
• Apply by brush or spray in 2–3 thin coats for best performance

What are the environmental and safety advantages of this water-based converter?

Being water-based and low-VOC, the product emits minimal odor and is easier to clean up than solvent-based coatings, reducing ventilation needs and cleanup hazards. This makes it a better option for DIYers and professionals working in garages, workshops, or shipyards who want reduced fumes and simpler wet cleanup.

• Contains under 1% VOC for lower airborne emissions
• Non-toxic formula with water cleanup—no harsh solvents required
• Low odor improves comfort during application
• Recommended use within 72 hours after opening for optimal storage stability

How should I apply it to get a long-lasting finish?

Stir thoroughly before use and apply two to three thin coats rather than one heavy coat. Maintain recommended drying times between coats, and if you plan to paint over it, wait until full cure; otherwise the converted surface performs well as a protective black finish.

• Remove loose scale and heavy rust with a wire brush or scraper
• Stir product and apply with brush or spray; thin coats adhere better
• Touch-dry in 2–4 hours, fully cured at about 24 hours under normal conditions
• Use within 72 hours of opening for best storage results

Who this is for: Autosel 2-in-1 Rust Converter & Metal Primer is intended for vehicle restorers, fleet and trailer owners, marine maintenance crews, and industrial maintenance teams who need a practical, lower-VOC solution to treat and protect corroded metal. It suits both hands-on DIYers who want straightforward application and professionals seeking a durable, heat- and UV-resistant coating that reduces prep time while delivering lasting corrosion defense.
