A classic firearm finish, bluing has been a staple in the world of gun maintenance and restoration for generations. While various bluing techniques exist, cold bluing provides a straightforward and accessible method for achieving a protective and visually appealing finish. Among the available options, Birchwood Casey Perma Blue stands out as a popular choice for its ease of use and effectiveness. This comprehensive guide will walk you through the **Birchwood Casey Perma Blue instructions**, ensuring you have the knowledge and skills to achieve a professional-looking blued finish on your firearm or metal components.
Embracing the Art of Cold Bluing: Understanding the Fundamentals
Before diving into the practical steps, understanding the principles behind cold bluing is essential. Cold bluing involves applying a chemical solution that reacts with the metal’s surface, creating a layer of iron oxide (magnetite), which provides corrosion resistance and a characteristic dark finish. Unlike hot bluing, which involves immersing the metal in a hot chemical bath, cold bluing solutions, like **Birchwood Casey Perma Blue**, can be applied at room temperature, making it a convenient option for hobbyists and gun owners.
The effectiveness of the process hinges on meticulous preparation and the correct application of the bluing solution. The key to success is a clean, grease-free surface and a thorough understanding of the steps involved. Cold bluing is an excellent way to touch up existing bluing, restore small areas, or blue entire parts.
Essential Precautions and Gathering Your Materials
Your safety and the success of the project hinge on proper preparation. Before commencing, assemble the following materials and adhere to these crucial safety precautions:
Prioritize eye protection. Always wear safety glasses or goggles. This is non-negotiable.
Protect your hands. Don rubber gloves. This is critical to prevent skin irritation from the chemicals.
Ensure adequate ventilation. Work in a well-ventilated area to avoid inhaling any fumes. Consider a well-ventilated workshop, or open windows and doors when applying the solution.
The Arsenal: Assembling Your Necessary Supplies
Gathering the right supplies is the next step in mastering these **Birchwood Casey Perma Blue instructions**. Here’s a comprehensive list:
The Star of the Show: **Birchwood Casey Perma Blue** solution. Ensure you have a fresh bottle.
Degreasing Agent: You’ll need a powerful degreaser to remove oils, grease, and contaminants. Options include specialized gun degreasers (like Birchwood Casey Cleaner & Degreaser), or if those aren’t available you can use common household degreasers. Ensure it is safe for metal parts.
Surface Preparation Tools: Steel wool or a fine abrasive pad (like a Scotch-Brite pad) is necessary for smoothing the metal.
Application Aids: Clean cotton swabs or applicator pads (cotton balls, Q-tips) will be used to apply the solution.
Rinsing Medium: Clean water for rinsing.
Preservation and Protection: Rust preventative oil (like Birchwood Casey Barricade or a similar product) is a must.
Containers (Optional): You may need containers for degreasing and rinsing, depending on the method you choose.
Drying Materials: Soft, clean cloths or paper towels for drying and oiling are also necessary.
Sandpaper: Various grits of sandpaper (optional, but highly recommended for surface preparation) will help you with smoothing out your metal parts.
Preparing the Metal’s Foundation: The Cornerstone of Success
Preparation is more than half the battle when using these **Birchwood Casey Perma Blue instructions**. The success of your bluing job depends directly on your preparation efforts. Let’s begin with a clean slate.
If your part can be safely disassembled (e.g., removing a slide from a pistol), do so. This allows for a more thorough cleaning and easier access to all surfaces. If the part is a firearm, you must ensure that it is unloaded and safe.
Degreasing: The Unsung Hero of Bluing
Degreasing is the single most crucial step. A single drop of oil or grease will sabotage your results.
Begin by thoroughly degreasing the metal surface. Follow the degreaser’s manufacturer’s instructions. This may involve soaking the part in the degreaser, or wiping it down thoroughly. The goal is to remove any trace of oil, grease, or any other contaminants.
After degreasing, rinse the metal thoroughly with clean water (or the rinsing solution recommended by your degreaser manufacturer).
Avoid touching the metal with your bare hands after degreasing. Handle it with clean gloves or by holding it by the edges.
Surface Preparation: Achieving the Perfect Finish
Once degreased, it’s time to prepare the surface for bluing. The texture of the metal’s surface will determine the look of the finished bluing.
Smoothing the Surface: Start by using sandpaper to remove any rust, scratches, or imperfections. Begin with a coarser grit sandpaper (e.g., 220 grit), and work your way up to finer grits (e.g., 400, 600, or even 800 grit) to achieve the desired smoothness. The smoother the surface, the more even the bluing will be.
Polishing with Steel Wool or Abrasive Pad: After sanding, use steel wool or an abrasive pad to polish the metal further. This will refine the surface and help to create a consistent texture. This step is especially useful for removing any fine scratches from the sandpaper and helping with a smooth and uniform finish.
Cleaning After Surface Preparation: After any sanding or polishing, you must thoroughly degrease the metal again. Any dust or residue from the sanding process will interfere with the bluing process.
Applying Perma Blue: The Moment of Truth
Once the metal is prepared and spotlessly clean, it’s time to apply the **Birchwood Casey Perma Blue** solution. This is where the magic happens.
How to Apply: Shake the bottle of **Birchwood Casey Perma Blue** vigorously before use. With a cotton swab or applicator pad, apply a thin, even coat of the solution to the prepared metal surface. Avoid applying too much solution, as it can cause unevenness and blotching.
The Reaction: The metal will begin to darken almost immediately. Depending on the metal and the specific **Birchwood Casey Perma Blue instructions**, the color change can range from gray to dark blue to black.
The Wait: Allow the solution to react with the metal for the time specified in the manufacturer’s instructions. This is usually a minute or two. Do not rub the metal while the solution is reacting.
Small Batches: Applying Perma Blue in small sections helps you manage the process. It can be helpful to apply a small amount and then rinse and oil.
Neutralizing and Finishing: Sealing the Deal
The reaction is complete, and now it’s time to protect your work.
Rinsing: After the recommended waiting time, rinse the metal thoroughly with cold, clean water. This neutralizes the chemical reaction and stops the bluing process.
Drying: Gently pat the metal dry with a clean, soft cloth or paper towel. Avoid rubbing the surface excessively, as this can remove the bluing.
Oiling: Once the metal is completely dry, apply a thin coat of rust preventative oil, evenly over the entire blued surface. This protects the new bluing from corrosion and helps to enhance its appearance. Allow the oil to sit for a few minutes, then wipe off any excess.
Repeat Oiling: For optimal protection, apply a second coat of oil after a few hours and again a day later. This will ensure the bluing is fully sealed and protected.
Common Challenges and Their Solutions
Even with careful preparation, there might be problems. Here are some common issues you might encounter while following these **Birchwood Casey Perma Blue instructions** and their fixes:
Uneven Bluing: This is a common issue, often caused by poor surface preparation, uneven solution application, or oil on the surface. The solution: re-prepare the surface and re-apply, paying close attention to even application and ensuring that the metal is completely oil-free.
Streaking or Patchiness: This can be caused by uneven application or incomplete degreasing. Corrective actions: re-prepare the metal, and ensure you apply an even coat of solution.
Fading or Quick Wear: This happens when there isn’t enough oil on the metal to protect it from rust. Solution: Re-oil more frequently and handle the blued parts with care.
No Color Change: The metal wasn’t properly prepared or degreased. The product itself may also be expired. Solution: re-prepare the metal thoroughly, or if the product is old, buy a new one.
