Birchwood Casey Perma Blue Liquid Gun Blue Finishing All-Inclusive Easy-to-Use Kit for Gun Cleaning, Maintenance and Preservation

I recently used the Birchwood Casey Perma Blue Liquid Gun Blue, and it exceeded my expectations. Here’s my detailed review: Pros: - Easy to Use: The application process is straightforward, even for someone without much experience. The instructions are clear, and the whole process from cleaning to bluing took about an hour. - Excellent Results: The finish is deep, rich, and uniform. It gave my firearm a professional-looking blue-black finish that significantly enhanced its appearance. The coverage is smooth, with no streaks or blotches. - Durability: After applying the Perma Blue, I noticed that the finish is quite durable. It stands up well to handling and use, showing no signs of wear or chipping after several weeks of use. - Cost-Effective: This product offers great value for the price. A little goes a long way, and I was able to complete the bluing of an entire rifle with plenty left over for future touch-ups or other projects. - Versatility: While it’s designed for firearms, the Perma Blue can also be used on other metal items that need a durable, attractive finish. I’ve used it on some old tools and knife blades with equally good results. Cons: - Strong Odor: The only minor downside is the strong chemical smell during application. It’s important to use it in a well-ventilated area or outdoors to avoid inhaling fumes. Conclusion: Birchwood Casey Perma Blue Liquid Gun Blue is an outstanding product that delivers professional-quality results at a fraction of the cost. Its ease of use, excellent finish, and durability make it a top choice for anyone looking to blue their firearms or other metal items. Overall, I rate this product 5 stars. It’s a must-have for anyone needing a reliable and effective bluing solution.

Very happy with the results using this to restore and reblue an old 10-22 barrel. The finish came out looking factory new. The process is easy, but involved. It takes a lot of prep work, sanding, and scrubbing off the old finish and any rust. Then spreading on the bluing, quickly rinsing your part off, more scrubbing, rinsing, and reaplying. It took me about 5 coats of the bluing to get a factory-like finish. What really made the difference was very lightly polishing the barrel after each coat with the supplied steel wool. In the end, my barrel shines like a mirror with a great blue finish. I would not hesitate to use this again. I will just have to wait and see how it holds up, and will update as necessary.

My handgun had developed significant scratches from years of concealed carry, regular use, and transport. After researching options, I found that stripping and reapplying the bluing was the right solution—and this kit delivered exactly what I needed. It includes three bottles: a cleaner/degreaser, a bluing remover, and the permanent blueing solution. All worked flawlessly. After completing the process, I applied a light coat of gun oil, which brought out a deep, rich shine that looks better than factory-new. If you’re looking to refinish your firearm, look no further. The instructions are clear and easy to follow—even for a first-timer. And if you make a mistake? No stress. The process is completely reversible at any point by returning to step one. You simply strip and start again. This kit makes it practically foolproof. I couldn’t be happier with the results.

Great kit for a quick re-bluing of a gun barrel. It is not going to give the factory look, but it will be close. I used it to re-blue some old rusted firearms that were handed down to me.

Works perfectly as advertised. I have purchased twice, because I have used it on so many products.

Good blueing kit. Have used this many times

I found a gun, it is 100 years old, it had been stored in a closet for more than 50 years untouched. It actually had more staining than rust, however once cleaned and left to dry out it began to rust terribly. I opted for this product. 1) I’m not an armorer, but with ease I was able to take the gun completely apart. This began the cleaning phase, my effort was of course to physically clean the gun, 3 days later I opened the cleaner and began the process of removing all the oils from me, easy task, no issues, everything went perfectly. 2) Now we begin removing the original blueing and any rust that was left. Okay I had watched a video, and with all the reviews cleanliness is the most important thing. This product worked amazing with a rag I basically just wiped the gun chrome, of course I used steel wool, with little effort, I could now see the original metal, and was about to work the tough spots and any dings I could find. Two days later, all the way through 1200 grit sandpaper and the green buffing compound and an industrial buffing wheel I could see myself perfectly in all of the metal, funny but everyone who saw it thought it looked beautiful chrome. 3) Reblueing-arrrrrr! Coat and little to nothing, reclean, steel wool, blueing, 6 coats later I’m on the Internet trying to get any advice on why this is not working, along comes Bubba44mag who says that the most important thing about re-blueing is heat. This is not in the instructions and like stain turns out to be important. Bubba said place the metal in the oven heat to 350f and this will be amazing more consistent etc, well I try not to place things in the oven, so I went to the gas log turned it on and hung up all the pieces for 2 days, to get heat through the metal, instantly fixed everything, 1 coat and the barrel looked brand new, not only the color but the blueing this time was perfectly smooth, so I rehung it to dry, cleaned again and ran another coat, beautiful, then rehung everything. 4) My experience with guns has always revolved around working the tool, while a professional gunsmith takes care of the details, obviously we have to be able to communicate. When the guns go to a place where maintenance may suffer there are rules, and the most important rule is cleanliness number 2 is blueing funny but this was part of my job, and these people just taught me why. In the words of a great man, SFC Keyes oil and heat condition the metals not on the outside but through the metal, so I used the oil wipe that came in this kit, along with the fireplace, now imagine the barrel is so shiny black, I wanted to send a picture to a friend, and when I touched the barrel it was dry, so I rewiped it and started pushing the oil into the barrel, I’ve now decided that this step should take a couple of days. Have fun!

It’s okay. Wish I’d sprung for a kit with a little kore quality, but I used Birchwood Casey bluing kits all the time 20 years ago and back then it was a superior product. I’m bluing a brand-new hexagonal .50 cal blackpowder rifle barrel made of high-carbon steel. Something has changed with this kit… this isn’t the same kit I used a few years ago. The chemicals don’t seem to be as strong, and it took way too many applications to get close to the blue I wanted, and it’s still not quite dark enough. Back in the day, 8-10 applications of BC’s bluing agent turned high-carbon barrels a deep blue-black. Not anymore. Shame, because I appreciate USA-made products. But I’ll be researching and speaking with the gun guys at the shop, seeking a better product than this. It almost did the job, and the instructions are clear (full of typos but legible) and the included non-chemical components were adequate for the job. I’d pay more for a stronger, more effective product.

Product did a great job! My 1965 rifle looks brand new from 5 feet away. Any closer your can see my mistakes. A few tips I will say: -put all solutions into a small bowl, don't dip applicator into the bottle because it will contaminate the whole bottle. -After decreasing for bluing, a bit of acetone helps a lot to clean and evaporate and water. -For the bluing solution it's easier to use a facial pad or something other than the stick applicator provided. Makes it less likely to streek. -don't try to do large pieces like the barrel in 2 sections at a time; you will never be able to blend it in smooth and will be able to see exactly the 2 sections. Just do the whole barrel at once and tape off the receiver to avoid runs. Amazing product gave new life to my old firearm and it really looks great! Love it

Buen producto y entrega rapido

Ya lo avía usado antes es bueno

Complete kit of materials. Just add gloves and you are ready to go. Did a real nice job. Make sure the remover is used in a well ventilated area. I did the bluing application 3 times and got a real nice finish.
