Understanding Gun Bluing
The Basics of Gun Bluing
At its core, gun bluing is a controlled oxidation process. It’s a chemical reaction where the steel of the firearm’s surface interacts with chemicals to create a layer of magnetite (iron oxide, Fe3O4). This magnetite layer isn’t just a cosmetic enhancement; it acts as a protective barrier, shielding the steel from rust and corrosion by preventing direct contact with moisture and oxygen.
Different Bluing Methods
There are several types of gun bluing, each with its unique application and results. Hot bluing, perhaps the most durable method, involves immersing the firearm in a hot alkaline salt solution, usually at temperatures exceeding 280 degrees Fahrenheit. Rust bluing, another time-honored method, uses a series of controlled rusting and boiling steps to create a rich, deep blue finish. Cold bluing, as its name suggests, is a process that doesn’t require high temperatures. It works by applying a chemical solution directly to the metal surface, resulting in an instant or relatively quick formation of the protective magnetite layer.
The Role of Bluing
Beyond aesthetics, bluing is a crucial aspect of firearm maintenance. Without a protective finish, steel firearms are susceptible to rust, which can compromise their functionality, accuracy, and longevity. It’s a fundamental aspect of responsible gun ownership and firearm care.
What is Super Blue?
Introducing Super Blue
Super Blue is a specific cold bluing solution, designed for ease of use and effective results. It’s a popular choice among firearm owners for its affordability and accessibility.
The Composition and Benefits
The exact chemical composition of Super Blue can vary slightly depending on the manufacturer, but it typically contains compounds that react with the steel surface to create the protective magnetite layer. Its user-friendliness is a major draw; it can be applied at home with minimal equipment. The quick application time and ability to perform touch-ups are also advantageous, allowing you to address scratches, wear, and other minor imperfections. The price point also makes Super Blue an attractive option.
Comparison with Other Cold Bluing Solutions
Different brands of cold bluing solutions utilize similar chemical principles but can vary in effectiveness and the resulting finish. Super Blue generally strikes a balance, offering a good combination of ease of use, effectiveness, and a reasonable price. Always remember to follow the manufacturer’s instructions when applying any cold bluing solution.
Preparing Your Firearm for Bluing
Safety First
Before even considering applying Super Blue, safety must be your paramount concern. Always wear appropriate safety gear, including eye protection and chemical-resistant gloves. Working in a well-ventilated area is also crucial to avoid inhaling any fumes.
Disassembly
Disassembly is usually needed for a complete bluing. The firearm (or the parts you intend to blue) needs to be disassembled, removing all of the components that are not being blued. This is important to get all of the parts in the application. Consult your firearm’s manual and the recommended disassembling methods before beginning.
Degreasing
The first step is thorough degreasing. Use a dedicated degreaser designed for firearms, or a strong solvent like acetone or denatured alcohol. Follow the instructions provided with the degreaser, which might involve soaking the parts or using a spray-on product. After degreasing, thoroughly rinse the parts with clean water and dry them completely.
Rust Removal
If there’s any rust present, it must be removed before bluing. Light surface rust can often be removed with fine steel wool or a specialized rust remover. For more severe rust, you might need to use a more aggressive abrasive or consider professional rust removal. Make sure to neutralize any rust remover used.
Surface Preparation
After degreasing and rust removal, the surface needs to be prepared. Any scratches or imperfections will be visible after bluing, so polishing or sanding to remove them is vital. Use progressively finer grit sandpaper to achieve a smooth, even surface. The smoother the surface, the better the final finish will appear.
Applying Super Blue
Materials Needed
Gathering all the necessary tools and materials is an essential step before you start the application. You’ll need the Super Blue solution itself, a clean applicator (cotton swabs, cotton pads, or a soft cloth are common choices), clean water for rinsing, a container for rinsing, a heat source to dry, and lubricating oil. The choice of applicator can affect the final finish, so experiment to see what produces the best results for you.
The Application Process
Now it is time to apply Super Blue. The exact application method will vary slightly depending on the product and your preferences. Always follow the manufacturer’s instructions. Typically, you apply a thin, even layer of the Super Blue solution to the prepared metal surface. Apply the solution in a single direction, avoiding a back-and-forth motion. Even coverage is the key to an even finish, so take your time. Some users prefer to apply the solution in light, even coats, while others find that applying a single, heavier coat is sufficient.
Waiting Time and Rinsing
After application, allow the solution to react with the metal. The manufacturer’s instructions will specify the ideal waiting time. The waiting time will often be just a few seconds to a minute. Avoid leaving it on the metal for too long as you do not want it to rust. After the specified waiting time, the part needs to be rinsed in clean water. This process helps stop the bluing process, removes any residue, and reveals the newly blued finish.
Drying and Multiple Coats
After rinsing, thoroughly dry the firearm parts. If it’s okay to apply heat, consider using a hair dryer or setting the metal outside to dry if there’s sunshine. This will help to set the color and enhance the durability of the finish. For a deeper, more durable finish, multiple coats of Super Blue may be required. Allow the part to dry between coats and lightly buff the surface with fine steel wool or a soft cloth after each application. Repeating the process of application, rinsing, and drying, will add layers to the bluing to offer a more durable finish.
After Bluing: Care and Maintenance
Neutralization and Oiling
After bluing, the process isn’t complete. You still need to take specific steps to ensure the longevity and effectiveness of your new finish. The first is neutralization. While Super Blue processes are generally self-limiting, a final neutralizing step is generally a good practice. Many recommend washing the blued parts with warm, soapy water and rinsing them well. Once the parts are dry, generously apply a high-quality gun oil to the blued surface. Oil provides a crucial layer of protection against moisture and corrosion, preventing rust from forming. Apply the oil evenly, wiping off any excess. Your firearm is ready to store after this step.
Storage
Proper storage is critical to preserving your firearm’s finish. Store your firearm in a dry, climate-controlled environment. Avoid prolonged exposure to humidity or drastic temperature changes. Store the firearm in a case or safe that is coated with a rust-preventative material, and keep the blued surfaces well-oiled.
Cleaning and Touch-ups
Cleaning the blued firearm is important, but the method should be gentle. Avoid harsh chemicals or abrasive cleaners, as they can damage the bluing. Use a soft cloth and a mild solvent. When cleaning, avoid using any chemicals that are not intended for gun use. For small scratches and imperfections, a touch-up with Super Blue is often sufficient. Simply clean the affected area, reapply the solution, and re-oil the surface. For more significant damage, professional re-bluing might be necessary.
Troubleshooting Common Problems
Spotty Finish
This is one of the most common issues. The primary cause is typically incomplete cleaning and degreasing. Retrace your steps. Re-clean and degrease the parts thoroughly. Ensure the surface is completely free of oil and residue before re-applying Super Blue. Uneven application can also cause a spotty finish, so try applying the solution more evenly and with more care.
Rust Formation
If rust appears after bluing, it usually indicates insufficient oiling or exposure to moisture. The most common cause is leaving the firearm wet after rinsing. Ensure that the firearm is thoroughly dried after each application. Re-oil the blued surface generously and store the firearm in a dry environment.
Streaking
Streaking usually results from uneven application. When applying the Super Blue solution, avoid a back-and-forth motion, and apply it in a single, smooth direction. Try a different applicator, such as a cotton swab or pad, to see if that improves the results.
Color Issues
The depth and shade of the bluing can be affected by the surface preparation and temperature. If the steel was not properly polished beforehand, the finish may look uneven. The correct temperature range for application also affects the finished color. If the color is not what you desire, try re-preparing the surface and re-applying, paying close attention to the details of the manufacturer’s instructions.
