Autosel Rust Converter & Metal Primer 35 oz Black — Converts Rust, Heat- and UV-Resistant

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 corrosion on metal surfaces.

If you need a single product to neutralize active rust and leave a paintable, protective finish, this 35 oz Autosel formula combines rust-converting chemistry with primer performance. It’s engineered to penetrate flaky rust, lock it in place, and resist outdoor stressors like sunlight, salt, humidity, and high temperatures—so metal parts from car frames to farm gates get a long-lasting barrier without expensive surface replacement.

How does this rust converter actually work on flaky or pitted metal?

The Autosel solution reacts with iron oxide to form a stable, tightly bonded layer that stops further oxidation and provides a keyed surface for topcoats. It’s designed to work on heavy rust, filling and sealing porous areas while preventing the rust from spreading.

• Chemical conversion of rust into a stable protective film
• Pentrates rust layers up to roughly 55µm without grinding
• Leaves a black primer-compatible finish ready for paint after curing

What steps are needed to apply it correctly?

Preparation is simple: remove loose scale and contaminants, then apply the product directly with a brush or roller for best coverage. It sets to a smooth black coating within a few hours and reaches full cure in about 48 hours, at which point you can overcoat with a topcoat if desired.

• Wire-brush or scrape away loose rust and flaking paint
• Stir and apply generously to rusted areas with a brush or roller
• Allow initial film to form in ~2 hours; wait ~48 hours before topcoating

Will this product withstand weather, heat, and road conditions?

Yes—Autosel’s formulation is built for outdoor exposure and mechanical wear. It resists UV degradation, road salts, humidity, and temperatures up to about 350°F, making it suitable for vehicle frames, trailers, and equipment used in demanding environments.

• Heat-resistant up to approximately 350°F (safeguards engine bay or chassis spots)
• UV- and salt-resistant for coastal and winter-road use
• Impact- and chip-resistant once fully cured

Can I use this on different kinds of metal and projects?

Autosel’s rust converter is formulated for a wide range of ferrous surfaces found in automotive, agricultural, marine, and home-maintenance applications. It acts as a corrosion inhibitor, sealer, and primer in one, simplifying repairs across many metal types and part sizes.

• Automotive frames, chassis, and underbody areas
• Trailers, gates, farm implements, and industrial machinery
• Tools, metal fences, marine fittings (non-submerged areas)

Who is this for: Autosel 2-in-1 Rust Converter & Metal Primer is suited for DIYers, professional mechanics, fleet managers, and property owners who need an efficient, durable way to stop rust without full panel replacement. If you want a single treatment that neutralizes rust, forms a primer-ready surface, and resists harsh outdoor conditions, this product simplifies maintenance and restoration tasks for vehicles, trailers, agricultural gear, and metal structures.
