Gun Bluing Services at Dirty Bird Industries
When a firearm is genuinely cared for, its finish tells the story. The deep, rich black-blue sheen you notice on well-kept rifles, shotguns, and handguns comes from gun bluing—a time-tested process that protects steel while delivering a clean, professional appearance. More than cosmetic, hot bluing helps guard against rust and wear, extending the life of your firearm and preserving its value.
At Dirty Bird Guns & Ammo, we specialize in professional gun bluing services that strike a balance between craftsmanship and durability. Every firearm we refinish undergoes a careful process: complete disassembly, surface preparation, immersion in heated bluing salts, neutralization, and a final oil bath. The result is a uniform finish that is both striking and resilient.
Whether you’re restoring a family heirloom, refreshing a trusted workhorse, or preparing a firearm for long-term use, hot bluing remains the industry’s preferred method. Unlike quick cold bluing kits that fade with handling, professional hot bluing provides depth, consistency, and protection you can trust for years to come.
If your firearm deserves the care of a proper finish, Dirty Bird Guns & Ammo is here to help. Explore our bluing services today and see how a professional touch makes all the difference.
What Is Gun Bluing?
Gun bluing is the process of creating a protective, corrosion-resistant finish on steel firearms through controlled oxidation. Instead of leaving the surface vulnerable to rust, bluing chemically transforms the steel into a stable oxide layer—much like the natural patina that forms on copper. This thin, darkened finish is both functional and aesthetic, giving firearms their signature deep blue-black appearance.
Bluing serves three key purposes:
- Enhanced appearance – A sleek, professional look that highlights craftsmanship.
- Rust resistance – Some protection against corrosion, though regular oiling and maintenance remain essential.
- Preservation of value – A proper finish helps firearms retain condition and long-term worth.
There are three main types of bluing in use today:
Cold Bluing – A fast and inexpensive option often applied using a gun bluing kit. Useful for minor touch-ups but lacks durability.
Rust Bluing – A traditional, painstaking process favored for antique or collectible firearms. It produces a rich, classic look but requires significant time and expertise.
Hot Bluing – The modern standard for most firearms. Performed by professionals, it delivers a uniform, durable, and long-lasting finish.
For most gun owners, hot bluing strikes the ideal balance between protection, appearance, and practicality.
Hot Bluing for Carbon Steel Firearms
Carbon steel remains one of the most common materials in firearm manufacturing, and hot bluing is the gold standard for protecting it. At Dirty Bird Guns & Ammo, we specialize in applying a deep, even hot blued finish to carbon steel rifles, shotguns, and handguns. This process not only enhances appearance but also adds a protective barrier against rust and wear. For shooters who want a professional finish that combines tradition and durability, carbon steel hot bluing delivers both.
Cold Blue Touch-Ups and Rust Bluing for Collectibles
Not every project requires a full refinishing. For minor scratches, worn spots, or areas that need quick attention, cold blue touch-ups offer a simple and effective solution. While not as durable as hot bluing, cold blue helps restore appearance and provides a short-term protective layer.
For high-value or antique firearms, rust bluing is often the preferred option. This meticulous process produces a deep, classic finish that collectors especially value. Rust bluing requires time and expertise, but it preserves authenticity while adding reliable protection—perfect for heirloom firearms that deserve special care.
Hot Bluing vs. Other Modern Finishes
While hot bluing remains the traditional choice for firearm finishing, today’s gun owners also have access to several modern alternatives—each with its own advantages. Choosing the right finish depends on whether appearance, durability, or corrosion resistance matters most to you.
Hot Bluing creates a classic deep blue-black finish that many shooters still prefer for its balance of aesthetics and function. It provides moderate rust resistance and is ideal for those who value authenticity and tradition. However, it requires ongoing care, such as oiling and proper storage, to maintain its protection.
Cerakote is a ceramic-based coating that offers one of the most durable and corrosion-resistant finishes available. It’s highly customizable, with endless color options, and provides excellent abrasion resistance. Unlike bluing, Cerakote sits on top of the metal rather than chemically altering it. Cerakote Services.
The military widely used parkerizing (phosphate coating) for decades. It produces a matte gray or black finish that is more corrosion-resistant than bluing, though less visually striking. It also holds oil well, improving protection.
Nitriding is a modern heat-treating process that hardens the surface of steel. It offers outstanding wear and corrosion resistance while maintaining a natural metallic look.
Each option has value, but hot bluing remains the go-to for a timeless, traditional finish, while Cerakote and nitriding excel for maximum durability.
The Hot Bluing Process
Hot bluing is the most reliable and widely used method for finishing modern firearms. The process works by immersing steel parts in heated salt baths composed of sodium hydroxide and nitrates, which chemically transform the surface into magnetite (Fe₃O₄)—a stable, black oxide layer. This transformation not only gives the firearm its signature deep blue-black finish but also provides a degree of rust resistance.
The hot bluing process involves several carefully controlled steps:
- Disassembly – The firearm is thoroughly taken apart to ensure every component is treated correctly.
- Surface Preparation – Old finishes, rust, and blemishes are removed. A finer polish produces a smoother, more refined result.
- Hot Salts Bath – Steel parts are submerged in bluing salts maintained at ~290–310°F, where the chemical conversion occurs.
- Neutralization – Parts are thoroughly rinsed to halt the chemical reaction and prevent damage.
- Oil Bath – Each component is coated with protective oil, sealing the finish and enhancing durability.
The outcome is a uniform, sharp-looking finish that holds up far better than cold bluing. With proper care, a hot blued firearm maintains its protection and polished look for years of reliable use.

Here is why you should choose DirtybirdUSA for Bluing Service?
Can you explain the different types of gun bluing we offer (cold, hot, rust bluing)?
We offer hot bluing of carbon steel, cold blue touch-ups, and rust bluing.
Do we specialize in any unique or rare bluing techniques?
In addition to typical bluing, we also offer rust bluing for nickel steel. It is a rare steel found in older firearms that has a very high nickel content, sometimes over 5%!
Are there aesthetic/customization options available (finish color, gloss vs. matte)?
Yes, we do offer different levels of polish. We offer from Matte to Mirror, sometimes called “Royal.” This polish isn’t just aesthetic; as the polish on steel increases, it becomes more corrosion-resistant. We are also able to “antique” the finish and make it appear older. We are also able to adjust our salt bath concentration to make the finish appear greyer, as opposed to the typical dark black/blue, for those looking for a more “tactical” gun.
What sets our bluing service apart from competitors?
We stand out because we specialize in authenticity. We strive to retain all markings, apply the original bluing with the original level of polish, and take special care to never round out edges or alter the gun. We strive to keep the gun as original as possible so that it comes out just how you remember it, without compromising its value, and without giving away our presence. However, we can also alter the originality if desired, by offering a lower or higher polish and/or a different technique, while still retaining the markings and form of the gun.
Do you offer a warranty or guarantee on the bluing work?
We offer a 100% satisfaction guarantee on our bluing. If you’re not satisfied with the outcome, we will make it right by redoing it. If, despite proper care, the bluing fades or rusts, we will also redo it. Of course, leaving your gun at the bottom of a lake or other clear negligence/lack of maintenance is NOT covered.
How much does gun bluing typically cost, and what factors influence pricing?
For bluing itself, whole rifles will be $650.00, excluding polish and cleaning. Whole handguns (including the frame) will be $325.00, excluding polish.
Whole firearm polish prices are as follows and include the cleaning:
– Matte: $240.00
– Low Satin (brushed look): $480.00
– High Satin (near mirror, high luster): $720.00
– Mirror: $1,000.00-$2,000.00+ (price will vary based on make/model)
– Polishing and bluing prices for parts alone will depend on how large the object is and the desired result.
Caring for a Blue Firearm
While bluing provides protection, it isn’t a complete shield against the elements. A firearm’s finish is only as strong as the care behind it, and regular maintenance is key to ensuring longevity.
To keep a blued firearm in top condition, follow these best practices:
- Apply a light coat of oil – After each use or cleaning, wipe the metal surfaces with quality gun oil to reinforce rust resistance.
- Control storage conditions – Keep firearms in a calm, low-humidity environment. Use dehumidifiers or silica packs in safes to reduce moisture exposure.
- Clean gently – Use soft cloths or non-abrasive pads to prevent scratches that can compromise the finish.
- Avoid harsh solvents – Strong cleaners may strip away protective oils, leaving the blued surface more susceptible to damage. Stick to gun-safe products.
When properly cared for, a professionally hot-blued finish can last for decades, preserving both function and appearance. Unlike cold bluing touch-ups, which fade quickly with handling, hot bluing creates a more durable foundation. Combined with consistent upkeep, this finish not only protects against rust but also helps maintain the firearm’s long-term value and performance.
FAQs on Gun Bluing Firearms
Got questions about gun bluing? We’ve gathered the most common answers to help you understand the process, benefits, and care of blued firearms.
Does gun bluing prevent rust?
Yes, but only partially. Bluing slows down rust formation, but firearms still require regular oiling to remain fully protected.
Can you blue stainless steel, brass, or aluminum?
No. Traditional bluing only works on carbon steel. Stainless steel, brass, and aluminum require different finishing techniques, such as Cerakote or anodizing.
How do you remove old bluing from a firearm?
Chemical strippers, abrasive polishing, or bead blasting can remove old bluing before refinishing. This step is included in professional bluing services.
Which is better: cold bluing, hot bluing, or rust bluing?
Hot bluing is best suited for modern firearms that require durability. Rust bluing is ideal for antiques. Cold bluing is suited for quick touch-ups.
What chemicals are used in gun bluing solutions?
Hot bluing uses sodium hydroxide and nitrate salts. Cold bluing typically uses selenium dioxide.
Is hot bluing safe for older or antique firearms?
It depends. Hot bluing may not be appropriate for delicate antiques—rust bluing is usually preferred for older firearms.
How long does a blued finish last with proper care?
Decades. With proper oiling and storage conditions, a hot blued finish can last the lifetime of the firearm.
How should a firearm be prepared before professional bluing services?
Ensure the firearm is unloaded, free of oil, and fully disassembled. Our team handles surface prep, rust removal, and refinishing.
Does bluing affect the accuracy or performance of a firearm?
No. Bluing only alters the surface finish of the steel and does not change the firearm’s tolerances, barrel rifling, or mechanical function. Its purpose is both protective and cosmetic, rather than performance-based.
