Birchwood Casey Perma Blue Liquid Gun Blue Bottle Review

Testing the Birchwood Casey Perma Blue Liquid Gun Blue Bottle: What You Need to Know

For anyone working with firearms, maintaining their finish is often as important as their function. My workshop has seen its share of bluing projects, from minor touch-ups to full restorations, and a reliable bluing solution is a must. This led me to the Birchwood Casey Perma Blue Liquid Gun Blue Bottle, a product with a long-standing reputation in the gunsmithing community.

My initial need for this specific product arose after a frustrating incident involving a dropped rifle barrel. The resulting unsightly scratch demanded a solution that was both effective and easy to apply without specialized equipment. While I considered a few generic cold bluing kits, their inconsistent results made me lean towards a trusted name.

Upon receiving the Birchwood Casey Perma Blue Liquid Gun Blue Bottle, my first impression was of a no-nonsense product. The bottle itself felt sturdy, and the liquid within had a characteristic chemical scent, signaling its intended purpose. There was an immediate sense of practicality; this wasn’t meant for show, but for work.

A brief comparison with a local gun shop’s in-house bluing service crossed my mind, but the cost and turnaround time made a DIY approach far more appealing. My immediate reaction was one of cautious optimism—would this liquid blue live up to its storied reputation?

Real-World Testing: Putting Birchwood Casey Perma Blue Liquid Gun Blue Bottle to the Test

My primary testing ground for this bluing liquid was my home workshop, a space that mimics the conditions of many hobbyist gunsmiths. I specifically chose a worn lever-action rifle, a firearm with plenty of surface area and historical character that could benefit from a touch-up. The process involved thorough cleaning and degreasing, crucial first steps that I know are non-negotiable for any bluing job.

The liquid was applied using cotton swabs, working in small sections to achieve an even application. I noted its consistency; it’s not overly thick or thin, making it manageable for controlled application. While the instructions emphasize avoiding stainless steel and aluminum, my test subject was carbon steel, and the liquid showed good adherence.

Over several applications, I observed that it took time to build up the desired blued finish. This is not a quick “spray and done” product; it requires patience and multiple passes. The finish developed from a somewhat reddish-brown to a deep blue-black, precisely as advertised.

For extended use and reliability, I revisited the rifle after several weeks of it sitting on the gun rack, exposed to typical workshop air and occasional handling. There were no signs of the bluing lifting or flaking. The applied finish remained consistent and adhered well to the underlying steel.

Compared to my experiences with some less reputable cold bluing kits, this one proved far more durable. Those cheaper alternatives often faded or wore off easily, especially in high-contact areas. Maintaining the blued surface required nothing more than a light oiling, much like any other blued firearm.

Extended Use & Reliability

Weeks turned into months, and the rifle continued to hold its blued finish remarkably well. I intentionally subjected a small, discreet area to a light rub with a rough cloth, simulating minor abrasive contact. The Perma Blue held firm, showing only a very subtle dulling that easily buffed out with a touch of gun oil.

Maintenance has been straightforward. A light coat of quality gun oil after each handling session has kept the blued areas protected from potential rust or wear. Cleaning is just as simple as with any other blued firearm; a quick wipe-down with a silicone cloth is usually sufficient.

When compared to the notoriously fickle bluing often found on vintage firearms, this solution offered a predictable and robust outcome. It doesn’t quite replicate the deep, oven-baked luster of a professional hot bluing job, but for a liquid application, its longevity and appearance are commendable. I’ve found that using the accompanying neutralizing solution (sold separately but recommended) significantly aids in halting the chemical process and ensuring a stable finish.

Breaking Down the Features of Birchwood Casey Perma Blue Liquid Gun Blue Bottle

Specifications

This particular offering from Birchwood Casey comes in a 32 oz bottle, which is a substantial amount for extensive bluing projects or frequent touch-ups. The liquid itself is specifically formulated for bluing steel, and it’s crucial to remember that it will not work on stainless steel, aluminum, or other non-ferrous metals. This limitation is clearly stated and is standard for most cold bluing solutions.

The significance of the 32 oz volume is its cost-effectiveness for larger projects or shops that regularly perform bluing work. A smaller quantity might suffice for a single firearm touch-up, but for multiple guns or more involved re-bluing, this larger bottle provides excellent value. The chemical composition is designed to react with the iron in steel, creating a stable, non-reflective blue-black finish.

Performance & Functionality

The primary function of the Birchwood Casey Perma Blue Liquid Gun Blue Bottle is to re-blue steel surfaces, and it performs this task admirably, albeit with caveats. Its core strength lies in its ability to create an even, non-streaky finish when applied correctly. I found that multiple thin coats are far more effective than trying to achieve the desired color in one go, which is a common pitfall for beginners.

A significant strength is its capacity for touching up scratches and worn areas. It blends remarkably well with existing bluing, making repairs far less noticeable. However, it’s important to manage expectations; this is a cold bluing process, and it won’t replicate the depth or luster of a professional hot bluing job. It provides a functional, protective, and aesthetically pleasing finish suitable for maintenance and minor restoration.

Design & Ergonomics

The design of the Birchwood Casey Perma Blue Liquid Gun Blue Bottle is purely utilitarian. It’s a simple, durable plastic bottle with a secure screw-top lid, designed to keep the chemical safely contained. The bottle’s shape allows for easy pouring into secondary containers or direct application from the spout, though I prefer using cotton swabs or applicator pads for more control.

Ergonomically, the bottle itself is easy to handle and pour from, even with gloved hands. The cap seals well, preventing evaporation and accidental spills, which is a major plus when dealing with bluing solutions. There are no complex controls or grips; its design prioritizes functionality and safety.

Durability & Maintenance

The durability of the applied bluing finish is impressive for a cold bluing product. Properly applied and maintained, it offers good resistance to light wear and handling. The key to its longevity lies in proper preparation of the metal surface and consistent, light oiling after application.

Maintenance of the product itself is minimal. Keeping the bottle sealed tightly and stored away from extreme temperatures will ensure its effectiveness over time. I haven’t encountered any issues with the liquid degrading prematurely when stored correctly. Potential failure points for the applied finish would stem from aggressive cleaning agents or significant physical abrasion, not from the bluing solution itself breaking down.

Accessories and Customization Options

The Birchwood Casey Perma Blue Liquid Gun Blue Bottle is sold as a standalone product. However, for optimal results, I highly recommend purchasing the Birchwood Casey Gun Stock Finishing Kit or similar accessory packs. These often include essential items like neutralizing solutions, cleaning agents, degreasers, and fine steel wool, all crucial for proper surface preparation and finishing.

While there aren’t direct customization options for the bluing liquid itself, the application can be customized. Using different applicators like cotton swabs, wool pads, or even fine brushes allows for varying degrees of coverage and texture. For example, dabbing it on with a cotton swab is perfect for tiny scratches, while a wool pad can help blend larger areas.

Pros and Cons of Birchwood Casey Perma Blue Liquid Gun Blue Bottle

Who Should Buy Birchwood Casey Perma Blue Liquid Gun Blue Bottle?

This product is ideally suited for firearm owners, hobbyist gunsmiths, and anyone who performs their own firearm maintenance. It’s perfect for those who need to perform minor cosmetic repairs on blued firearms, such as touching up holster wear or minor scratches. If you have a carbon steel firearm that has seen better days and you’re looking for a practical, cost-effective way to restore its finish, this is a solid choice.

However, individuals looking to completely re-blue a firearm with the intent of achieving a factory-fresh, high-gloss finish might find this product to be a stepping stone rather than the final solution. Those who are uncomfortable with chemical applications or proper metal preparation should seek professional services. For users who need to blue non-ferrous metals like aluminum or stainless steel, this product is entirely unsuitable.

For those embarking on a bluing project, I strongly recommend pairing the Birchwood Casey Perma Blue Liquid Gun Blue Bottle with their neutralizing solution and a good quality degreaser. Having a supply of fine steel wool (0000 grade is ideal) and lint-free cloths is also essential for proper surface preparation and buffing.

Conclusion on Birchwood Casey Perma Blue Liquid Gun Blue Bottle

The Birchwood Casey Perma Blue Liquid Gun Blue Bottle is a workhorse product that delivers on its promise of providing a reliable cold bluing solution for steel firearms. Its ability to effectively touch up scratches and worn areas makes it an invaluable tool for maintaining the aesthetic and protective qualities of a blued gun. While it doesn’t replicate the depth of professional hot bluing, its ease of use, durability, and cost-effectiveness make it an excellent option for DIY firearm maintenance.

The 32 oz quantity offers significant value, especially for those who frequently work on firearms or have larger projects. It’s a product that demands a bit of patience and proper technique, but the results are consistently good for a cold bluing application.

I would confidently recommend this liquid bluing to any firearm owner looking to perform their own cosmetic touch-ups or minor re-bluing. Just ensure you prepare your metal surfaces meticulously, follow the application instructions carefully, and have realistic expectations for a cold bluing process. It’s a dependable solution that has earned its place in my workshop.
