Formula 47: Old Masters Rust Bluing Solution

Revive the classic, deep finish of vintage firearms with the efficiency of a modern workshop.

Formula 47 by C.S. Elliot Trading Company Ltd. is a premium express rust bluing solution developed by a gunsmith and engineered to deliver the rich, durable, finishes demanded by true craftsmen. Whether you are restoring Grampy's heirloom or completing a custom build, Formula 47 provides the perfect bridge between old-world aesthetics and modern efficiency.

Unlike traditional slow rust methods that can take days or weeks of waiting, our proprietary express formulation is designed to react swiftly and predictably, significantly cutting down shop time without compromising the depth or durability of the final finish. It produces a tough, highly corrosion-resistant oxide layer that blends seamlessly with vintage steel while offering traditional wear resistance.

Why Choose Formula 47?

• Express Formulation: Drastically reduces turnaround time in the shop, allowing you to complete multiple carding and boiling cycles in a single session.
• Deep, Traditional Color: Achieves that sought-after, authentic blue-black luster characteristic of classic firearms, avoiding the artificial look of cold blues.
• Consistent & Predictable: Formulated for smooth, even application, minimizing the risk of streaking or splotching on critical metal surfaces.
