  1. Use gloves to prevent staining of hands.

  2. Scrape or wipe off dirt & oil. Sand or wire brush rusted surface.

  3. Shake well before using.Pour a small amount of Permatex® Rust Treatment into a separate disposable container. Do not return unused material to bottle, or dip the applicator into the original bottle, as contents may be prematurely activated.

  4. Brush or sponge on a thin layer using long thin strokes. Try to contain Rust Treatment to rusted area being treated as product will stain surrounding paint. Remove splatters with detergent and water immediately.

  5. A black coating will begin to appea rin 15-30 minutes. Apply a second thin coat within 20 minutes, to produce a uniform color.

  6. Allow 24 hours protected from moisture before top coating. Acrylic latex finish paints require a solvent-based primer/sealer before painting. Lacquer/enamel-base paints may be used without a primer.

  7. Clean brushes and other tools immediately after use with detergent/water.

  8. For Automotive Applications (NOT RECOMMENDED FOR AUTOMOTIVE EXTERIOR SHEETMETAL REPAIRS): Allow an extra 24 hours drying time to allow trapped moisture to evaporate before top coating. For a smooth finish, use sandable primer and sand with 220 grit or finer sandpaper before top coating.
