Overview

Permatex 81849 Rust Treatment is a fast-acting, one-step rust solution designed for metal surfaces across automotive, agricultural, and industrial equipment. It removes existing rust and forms a durable black polymer film that can serve as a paintable primer, especially when used with body filler or fiberglass components.

In practice, you brush or spray on the treatment, and within minutes the old rust is replaced by a protective layer that helps resist future corrosion.

That coating doubles as a primer, so you can topcoat with your preferred paint for a finished look. The film bonds with compatible paints and accepts additional coats.

Key benefits

  • Easy to apply by brush or spray, reducing prep time
  • Effective rust removal on many automotive surfaces
  • Rapid formation of a durable black coating that acts as primer
  • Protective primer that accepts paint for a finished look
  • Engineered to work with body filler and fiberglass components

Ideal uses

This rust treatment is built to handle a range of work environments and project types. It tolerates typical shop temperatures between 50°F and 90°F (10°C–32°C) during application, and surfaces up to 200°F (93°C) can be handled while the coating cures or sets.

  • Automotive applications, including frames, rails, and structural parts
  • Trucks, trailers, storage tanks, pipes, fences, bulkheads
  • Overheads, decks, hatch covers (topcoat with marine paint for exposed surfaces)
  • Agricultural equipment, plows, tractors, and snow removal gear

Application tips

  • Prepare a clean, dry surface by removing loose rust and dirt
  • Apply evenly by brush or spray; allow proper drying between coats
  • Paint over once fully cured to achieve your desired finish
  • Store the can upright in a cool, ventilated area away from heat

Note: Not recommended for automotive exterior sheet metal repairs. For best results, use within the specified temperature window (50°F–90°F) and on surfaces not exceeding 200°F.
