BROWNELLS - Classic Rust Blue, 4oz

Nothing adds the finishing touch of elegance and perfection to a fine firearm quite like the rich luster of a traditional rust blue finish. Nowadays, only a handful of master gunsmiths still practice the art of producing this fine, classic finish using proven recipes more than a century old. With our Classic Rust Blue, you too can achieve the “secret” rust blue so fitting when restoring older guns, especially soft-soldered double guns, or finishing modern, exhibition-grade custom pieces. Rust bluing doesn’t require a lot of expensive equipment and is actually easier for the home gunsmith and hobbyist to do than modern hot-bluing processes, while producing a deep, brilliant, finish that will outlast many modern alternative finishes. The process is time consuming, but for a quality firearm, the results are well worth the investment of time and effort.

Like the tried and true originals, our authentic formula is a precisely balanced concentration of bluing salts and acids that require diligent metal preparation and multiple applications to achieve the truly stunning metal finish you expect from rust bluing. The rich, blue-black coloration is obtained by boiling the parts in water and rubbing them down with steel wool after each application of formula. Follow the included step-by-step instruction booklet to produce the exquisite, “into-the-metal” finish achieved by master gunmakers of the 19th century. SPECS: 4 fl. oz. (118ml) net contents; complete instructions included.
