Rust Blue brand/solution?

chuck17 · 03-21-2009, 08:36 PM

I am not a chemist, but this is my understanding. Parkerizing was a brand name for a conversion process of the surface of the metal using zinc phosphate or manganese phosphate. The name parkerizing has passed into the language, like kleenex or band-aid. The zinc phosphate parkerized surface provides a gray surface and a finer crystalline structure, which is supposed to be a better surface for GunKote and other brands of spray-on finishes to adhere to. The manganese phosphate surface is a darker charcoal gray to black finish with a thicker crystalline structure. Many military weapons have been parkerized as it is an excellent finish to hold oil on the surface of the metal. Parkerizing is an easy finish to apply, but if you try it make sure to plug the bore. You can buy it from Brownells or Midway.

Hello, thanks for the answers. The zinc-Parkerized is to fill of the pits. The product is touched and how is filler processed? Can I shop also in Germany? Can you show me a precise link to this product? How is it processed? I am glad about your answers!

Is that this Zink Produkt ? http://www.autolackierbedarf.de/item...rspachtel.html

The Parkerizing process does not fill the pits, but rather changes the surface to a sandpaper-like finish which is good for the adherence of oil (or the spray-and-bake finish) to the metal. I hand sanded down the pitting and tried to contour the barrel and other parts as well as I could. The parkerizing does "soften" the appearance, but it doesn't fix the pitting.

The link that you provided is not it. That looks like "Bondo" which is an automotive body filler. I have seen a gun pit filler product made by, I think Lauer which makes the Dura-Coat product, but I have not used their products.
