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 paint that converts existing rust into a paintable, corrosion-resistant surface while serving as a primer in one application.

This heavy-duty 70.5 oz formula combines a rust reformer, encapsulator, and metal primer so you can treat corroded steel and finish in fewer steps. Designed for automotive, marine, trailer, and industrial use, the coating bonds to oxidized metal, seals out moisture and air, and cures to a durable black finish that tolerates heat, UV, and many chemicals. The low-VOC, water-cleanup formula is suitable for both DIYers and professionals who need reliable rust control without harsh solvents.

How does this product stop rust without sanding away metal?

Autosel’s chemistry reacts with iron oxide to neutralize active rust and create a stable, paintable surface, so aggressive grinding is not always necessary. After cleaning loose scale and grease, apply thin coats to allow the converter to penetrate and form a sealed layer that resists further corrosion.

• Converts rust to a stable substrate ready for topcoat
• Works directly on corroded surfaces—removes loose rust, not base metal
• Two to three thin coats recommended for complete encapsulation
• Dries to touch in 2–4 hours, fully cures within 24 hours

Can I use this as a primer and finish coat for automotive or marine parts?

Yes—this product combines primer and rust reformer functions, delivering a smooth black finish suitable as a final protective coat in many applications. For maximum longevity in harsh environments, you can apply a compatible topcoat, but the 2-in-1 formula often serves as both primer and long-term protective coating.

• Designed for chassis, frames, trailers, and marine metal surfaces
• Heat resistant to 350 °F (176 °C) and UV stable for outdoor use
• Accepts overcoating if additional color or gloss is desired
• Non-flammable, water-based for safer workshop use

What are the best application practices for reliable results?

For consistent performance, remove loose rust and contaminants, stir the container thoroughly, and apply 2–3 thin, even coats by brush, roller, or spray. Allow adequate drying between coats, and avoid heavy wet-film application, which can sag or prolong cure time.

• Clean surface of loose rust, dirt, and oil before applying
• Stir well and apply thin coats; recoat within recommended window
• Use within 72 hours after opening for best results
• Clean tools with water; low-odor, low-VOC formula (<1% VOC)

How durable is the finished coating in real-world conditions?

The cured paint forms a resilient, corrosion-resistant layer engineered to withstand heat, UV exposure, and many chemicals encountered in automotive and industrial settings. While excellent as a protective primer or finish, performance improves when used on properly prepared metal and when regularly inspected in severe conditions.

• Resists temperatures up to 350 °F (176 °C)
• UV- and chemical-resistant for outdoor and industrial exposure
• Provides a smooth, protective black finish that blocks moisture and air
• Water-based and easier to maintain than solvent-heavy systems

Who is this for: Autosel 2-in-1 Rust Converter & Metal Primer is aimed at automotive restorers, trailer and chassis maintainers, boat owners, and industrial maintenance crews who need an efficient, water-based rust treatment that doubles as a primer. It’s also suited to DIYers who want a low-odor, low-VOC option to stop rust and deliver a long-lasting black protective coating without multiple specialty products.
