Hot gun bluing, also known as hot bluing or hot tank bluing, is a popular method for restoring or enhancing the finish of firearms. It offers a deep, durable, and historically accurate finish, making it a favored technique among gunsmiths and hobbyists alike. This guide will delve into the world of hot gun bluing kits, helping you understand what they are, how to use them, and what to look for when making your purchase.
Understanding Hot Gun Bluing Kits
Hot gun bluing kits provide all the necessary chemicals and equipment for performing a hot bluing process at home. These kits typically contain:
- Bluing salts: These are the chemical compounds responsible for creating the blue-black oxide finish on the metal. Different kits may offer varying formulations, each with its own strengths and weaknesses. Some formulations are designed for specific metals or desired shades of blue.
- Cleaning supplies: Proper cleaning is crucial before and after bluing. Kits usually include degreasers, solvents, and possibly abrasive materials for preparation.
- Container: A suitable container is essential for heating the bluing salts and safely immersing the firearm parts. Some kits provide a specialized container, while others may require the user to source one.
- Safety equipment: Hot bluing involves working with chemicals at high temperatures; therefore, safety is paramount. Kits should include gloves, safety glasses, and possibly a respirator depending on the formulation. Always refer to the included safety data sheets (SDS) before beginning the process.
- Instructions: Detailed instructions are crucial for achieving a successful bluing job. Reputable kits will provide clear, step-by-step guides, often including troubleshooting tips.

Different bluing salts produce varying results. Some offer a quicker process, while others result in a deeper, more durable finish. Research the specifics of each kit to understand the trade-offs.
Kit Completeness:
Some kits are more comprehensive than others. Consider whether the kit includes everything you need or if you’ll need to purchase additional supplies separately.
Reputation of the Manufacturer:
Opting for a reputable manufacturer ensures better quality chemicals and clear instructions, increasing your chances of a successful bluing project. Look for reviews and feedback from other users before purchasing.
Cost:
Hot gun bluing kits range in price, reflecting the quality of materials and the completeness of the kit. While a cheaper kit might seem appealing, investing in a higher-quality kit can often lead to a better finish and a safer experience.
