Brownells Cold Blue, 32 oz

44/40 has long been a benchmark in the cold-blue industry and at Brownells, we are pleased to have acquired the original high-speed formula and its renowned name, reintroducing it to its dedicated users. The bluing action of 44/40 is remarkably effective; simply moisten a patch with 44/40, apply it and immediately remove it with a dry patch. The coloring process occurs instantaneously, penetrating deeply into the metal for a durable finish. Extended soaking or rubbing is unnecessary. Surface preparation is straightforward; for scratches, clean and degrease as usual, then apply 44/40. For bluing external or internal components, the process is equally simple. Achieve the desired surface finish, clean it and use the wipe-on, wipe-off method. 44/40 performs exceptionally well. Additionally, it is versatile for other tasks in the workshop. Its rapid action and dark color make 44/40 an excellent alternative to traditional layout fluids. It quickly darkens steel, enhancing the visibility of layout lines without the surface build-up of paint that could interfere with dimension readings and it does not peel or flake. Apply 44/40 to lathe and cutting tools before sharpening to clearly see grinding areas. Use it to age brass and copper in restorations or to reduce glare and reflection. With 44/40, you can accomplish a multitude of tasks. It is essential for your workbench; the highly active formulation ensures you can expertly touch up nearly any non-stainless gun steel and seamlessly blend the repair with the original finish.
