A traditional rust blue finish imparts an elegant and refined appearance to a high-quality firearm. Currently, only a select few master gunsmiths continue to practice the art of creating this classic finish using time-tested methods that date back over a century. With our classic rust blue, you can replicate the secret rust blue finish, ideal for restoring older firearms, particularly soft-soldered double guns or for completing modern, exhibition-grade custom pieces. Rust bluing does not require costly equipment and is more accessible for home gunsmiths and hobbyists compared to modern hot-bluing techniques, while delivering a deep, brilliant finish that surpasses many contemporary alternatives. Although the process is time-intensive, the results justify the investment of time and effort for a quality firearm. Our authentic formula, like the original methods, is a precisely balanced mixture of bluing salts and acids, necessitating meticulous metal preparation and multiple applications to achieve the stunning finish characteristic of rust bluing. The rich, blue-black coloration is achieved by boiling the parts in water and polishing them with steel wool after each application of the formula. By following the included step-by-step instruction booklet, you can achieve the exquisite, into-the-metal finish mastered by 19th-century gunmakers.
