Product Information

Instead of applying it broadly over large areas, make sure to apply it in a single swipe and then use a piece of steel wool to even it out.

You can even make your own DIY gun bluing kit by using the gun bluing ingredients such as blueing salts and solutions.What’s more, guns that are treated with the hot bluing process tend to hold up longer, so you’ll definitely want to consider giving this a shot depending on the state of your firearm. Treating with an oiled coating enhances the protection offered by the bluing. This process is also the only process safely used to re-blue vintage shotguns. Many double-barreled shotguns are soft soldered (lead) or silver brazed together and many of the parts are attached by that method also. The higher temperatures of the other processes as well as their caustic nature could weaken the soldered joints and make the gun hazardous to use. [4] Caution: It’s very important to note that the gun must not have any aluminum or any other non-steel parts, even a thin plating. It absolutely must be bare steel. This is because some alloys will react with the salt in the solution and give off extremely dangerous fumes. If raw aluminum goes into the mixture, fumes maybe the least of your worries. It will likely cause an explosion. The gun bluing process The process involves soaking of the gun part into a hot liquid potassium nitrate, which produces a uniformly colored finish. Like all other bluing methods, the most crucial step is metal preparation. Here’s the deal: if you let your gun rust without taking action to correct it, it will lose its value—and a lot of it.

Knowing this, you’ll want to do what’s necessary to make sure that your gun is working optimally at all times. The Birchwood Casey Super Blue comes in a 3 fl oz plastic bottle and is one of the best and most affordable gun bluing solution available online. Once the salt solution is bubbling away happily, it’s time to drop the pieces in. (It should be set on the highest temperature for best results, around 375 to 400° F.) Bear in mind that cold steel will cool the solution and it will take a few minutes for the temperature to rise again. A total of 10 to 15 minutes should be enough to get a nice finish on the gun. Getting the results you wantDespite this, you’ll find that it works better for guns that have lost significant amounts of their bluing.
