Download TDS NovaTuff Rust-Rehab Converter Prime Sealer


NovaTuff P-585 Rust-Rehab is a rust converter, primer, and sealer. It penetrates the rust to sound metal, chemically converting the rust to a tough black, non-removable, non-rusting magnetite and sealing it to the surface.

Rust-Rehab serves as a primer coat, ready for top coating or as a stand-alone protective coating. It is a flexible sealer and will not surface crack.

Rust-Rehab permanently converts surface rust on metal to inert black iron oxide and seals the metal surface. When used as a primer or topcoat, it is proven to protect untreated, bare metal surfaces against moisture and other corrosive elements.

Application Areas:

Rust-Rehab is suitable for use on metal surfaces on “any size” project involving Transportation, Marine, Industrial & Commercial, Farm and Home applications.


  • Dries to a tough black, non-removable, and non-rusting magnetite
  • Converts existing rust and prevents new oxidation
  • Reacts with rust to create a new long-lasting protected surface
  • Surface can be top coated for maximum protection in harsh conditions
  • Safe, no solvents, and low odors
  • Brush, Roll, or Spray pump application
  • Does not evaporate off the surface of metal
  • Rarely requires reapplication
  • Easy to apply

Benefits compared to phosphoric acid treatment:

  • Non-Polluting, Non-Toxic, Non-Corrosive, contains no Mineral Acids.

  • No shipping restrictions.
  • Chemically converts rust to magnetite, which is stable and non-rusting.


  1. Remove loose paint and rust scales and heavy buildup with a wire brush, leaving only a rusty base.
  2. IMPORTANT: Remove all oil, grease, salt, or water-soluble chemicals with a high strength detergent cleaner.
  3. Rinse well with fresh water and let dry.


Shake NovaTuff Rust-Rehab container thoroughly before opening. Measure the estimated amount needed for the job into a clean container. NOTE: Rust-Rehab cannot be returned to the original container due to rust contamination. Use of rubber or latex gloves and eye protection is recommended. Contact will cause temporary skin discoloration that will wear off over a short period of time; it is not permanent. For maximum penetration, work Rust-Rehab into rusted surfaces with a synthetic bristle brush. On large areas, apply Rust-Rehab to rusted surface with a roller, pump or airless sprayer. Overlaying Rust-Rehab over the non-rusting areas will not have a negative effect — it leaves a clear coating to protect clean area. For best results apply 2 thin coats of 3 wet mils each coat at a rate of 500 sq ft/gallon/coat within 40 to 60 minutes of each other and in a cross direction to previous coat. Allow Rust-Rehab to dry at least 24 hours before top coating. Rust-Rehab dries to a black matte finish.
