Product Description

KBS Rust Converter Overview

KBS Rust Converter easily converts a rusty surface into a black, inert primed surface that is ready for paint and compatible with most topcoats and also protects against future rust.

Surface Prep:

NOTE: The surface must be rusty.

KBS Rust Converter is not designed to use on any non-rusty surfaces or surfaces where you have a mix of rusty areas and non-rusty areas. Use a wire brush or sandpaper to remove as much loose and flaky rust as possible. If needed, clean the surface with KBS Klean.


For best results, use when can is between 50°F and 90°F (10°C and 32°C). ALWAYS WEAR PROTECTIVE GLOVES AND EYE WEAR when using KBS Rust Converter. Always use NIOSH/MSHA approved air supplied respirator.

Shake can at least one minute after rattle is heard and occasionally during use.

Spray surface with steady even strokes at a distance of 8 to 12 inches. A chemical reaction will cause the rust to turn black.

Allow 24 hours before applying a second coat or when topcoating with a different coating.

If clogging develops, turn sprayhead ¼ turn or remove and clean sprayhead slot. DO NOT stick pin or other objects into can opening. With can and sprayhead pointed away from you, reinsert sprayhead with a gentle twisting motion.

  1. Rust Converter

    Posted by Reviewed by: Randy Pilgrim from LAKE GEORGE on 7/21/2017 on 15th Feb 2020

    I've actually used this product when I was employed by Colorado Department of Transportation. We tested it on Salt/Sand V-boxes that fit into the back of our tandem dump trucks. I was amazed at how well it soaked into the rusty metal that was starting to flack off. Once applied, I would pressure wash the treated area the following day and you would not believe how well this lifts off the rusty metal.

  2. Sprays Great. Works Well.
