polishing

Polishing is the process of creating a smooth and shiny surface by rubbing it or using a chemical action, leaving a surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations.) In some materials (such as metals, glasses, black or transparent stones), polishing is also able to reduce diffuse reflection to minimal values. When an unpolished surface is magnified thousands of times, it usually looks like mountains and valleys. By repeated abrasion, those "mountains" are worn down until they are flat or just small "hills." The process of polishing with abrasives starts with coarse ones and graduates to fine ones.

    Revolver Polishing

    I have what is possibly a noob question. I recently just trade my .45 high point for a, Ruger Blackhawk .357. I’m looking to polish it, not necessarily trying to get a mirror shine, to make it look nicer. What’s a good brand or way to polish it? I’ve heard of Mother, Lucas Metal Polish and Flitz...

    I made a mistake in getting fine grade walnut media for brass polishing. I have roughly 10#-12# of the stuff. If you have a media blaster I believe this IS the stuff YOU want. OR, you can still polish brass with it, but it seems a bit dusty because of the fineness of it?

    Case polishing question

    Since we spend so much time making sure we reload carefully, i would like my brass to be easier to polish. Ive got the tumbler deal. But from the shoulder up most cases have a heavy black coating on it. Why?
