Gun Blue Metal Prep 2.5X Concentrated Quart

To got with the concentrated rugged 2.5X Shooter Solutions' Gun Blue, this is concentrated, too, in the same for ease in shipping. In other words, for like immersion use, add 1 and one half of store-bought distilled water, well that is what I like to do, have control of the initial reaction, VS 1 part of concentrate. 1.5 : 1.

However this will have to go UPS ground ORMD as Parkerizing.

As good as Shooter Solutions' Gun Blue is, for rare metal alloys and for non-polished harder tool steel, this will prep the steel so the Gun Blue will produce a normal finish, and reduce wipe-off on prepared wrought iron.

While most soft metals in use do not need this, some will, for example leaded steel from Europe.

While this will obliterate light rust and mill scale like the 4C bare metal prep, it will not leave an hard conversion coating the bluing can't go through.

It's use will be after a degreaser and water bottom-flowing-in and before the bluing

It cannot be used ahead of the stainless steel blue.
