    How do "you" finish bright brass?

    I am converting an empty 30-06 cartridge to a bullet pen. I am using this kit:

    (THIS IS NOT MY PEN, ONLY THE PICTURE THAT THE VENDOR SHOWS WITH THE KIT.)

    I will be using every thing in the kit except the casing shaped tube. This is a progress photo I sent to the customer. She gave me the casing because it was her fathers and she wants to give it to him for fathers day as gift pen.

    All the markings and labeling are for the customers benefit.

    The real casing of course does not have any protective coating on it. after I get it more or less shined up (I am leaving some distress on it) what would you recommend that I coat it with to keep it from tarnishing?

    Hey James...I found this over on doityourself.com.

    They are recommending lacquer...I wonder how it'll hold up on a pen?

    True brass is an alloy of copper and zinc. It tends to oxidize (tarnish) quickly when exposed to air, which is a major reason why most brass is given a clear coating of lacquer to prevent this condition. Most conventional polishes such as "BrassoŽ," "TwinkleŽ," etc. coat the raw metal with a thin film of oil to help inhibit future tarnishing. Additionally, most metal polishes contain solvents and detergents to remove the tarnish, mild abrasives to polish the metal, and oils to act as a barrier between the raw metal and air.
    Brass turns "black" when cleaning due to over-use and misuse of polish. The biggest challenge to the upkeep of most metals, including brass, is the removal and inhibition of tarnish. All substances, especially metals, oxidize when exposed to air. Once tarnish is removed, a chemical barrier should be created between the bare metal and the air to inhibit the process from re-occurring.
    Many people over-use and flood metal surfaces with polishes believing that they are better protecting the surface. The more polish, the more protection. Wrong assumption. More polish creates a smudging problem since fingerprints (human body oils) "dissolve" the solvency of the metal polish. Additionally, too much polish may discolor the surface. Only a trace amount creating a thin film should be applied. Therefore, an adequate amount of metal polish should be applied and spread out an amount on an absorbent rag. Then, let the rag dry out for a minimum of 24 hours before placement onto most metals. Apply this trace amount of polish with the grain of the brass with one hand while buffing it out in a rapid motion (creating friction) with the other hand. This burnishing action will harden the polish (like "spit shining" a shoe) and create a surface far more difficult to smudge or discolor.
    When dealing with "raw" brass instead of finished lacquered brass, the reaction between raw metal and chemicals can create the condition. The care of most metals is a two step process:
    1. Cleaning (for light soils): The use of isopropyl (rubbing alcohol) applied with the sponge side of a light-duty, "white-padded" scrubbing sponge with the grain of the door. In the event of tougher scuff marks, flip over sponge and gently agitate with the grain of the metal with the white scrub pad.
      For heavier soils: Dampen sponge side with water, and apply a light scouring low abrasion creme onto it. Work product into sponge, and then stroke it onto your door with the grain. Once completed, wipe surface thoroughly clean with a clean, soft rag. Once surface is cleaned, then go to the next step.
    2. Polishing: One of the best tools which provides just the right amount of oil onto metal is a "yellow" treated dust cloth. Wipe down brass with this cloth and then buff it dry with a soft, cotton cloth. This trace amount of oil in the cloth should not smear or discolor, especially after buffing.
    Lacquering can be done at home, but all old lacquer must be removed first, and the surface completely clean (no fingerprints or cleaner on it) before spraying the lacquer on evenly in multiple thin coats. It is hard to do well. Keep decorative items dusted and clean. Wash in sudsy, lukewarm water, rinse and dry. Never use hot water on lacquered items as it loosens the lacquer; do not polish them or soak them in water.
    Olive Oil. Brass will look brighter and require less polishing if rubbed with a cloth moistened with olive oil after each polishing. Olive oil retards tarnish.
    Tarnished Brass

    Unlacquered brass tarnishes when exposed to air. A weekly wiping with a little liquid ammonia on a soft cloth will help keep unlacquered brass shiny. Use a commercial cleaner (available in grocery or hardware stores) or a homemade cleaner (below) to remove tarnish. On antique brass, test the cleaning product to be sure of obtaining the desired effect. Some methods not only clean tarnish but also remove the mellow coloring of age that is desirable on old drawer pulls and other accessories.
    To polish antique brass pieces, wash in hot, soapy water to remove grime, wax, etc. Rinse and dry. Moisten a soft cloth with boiled linseed oil and rub on the brass surface until all the dirt and grease have been removed. Polish with a soft cloth. Very old brass items, especially if in poor condition, require special care. Consult museum experts for advice. To polish for a soft finish: wash in hot, soapy water, rinse and dry. Make a paste of whiting and boiled linseed oil. Apply with a soft cloth and rub to remove tarnish. Wipe off excess paste and polish with a clean cloth. To remove heavy tarnish, difficult stains and corrosion: wash in hot, soapy water or a weak ammonia and water solution and rinse. Dampen a soft cloth in hot vinegar, then dip in table salt and rub the brass, or make a paste of flour, salt and vinegar. You may need several applications. When the item is clean, wash in hot, soapy water, rinse and dry thoroughly, then polish with a cloth moistened with lemon oil. If preferred, dip a slice of fresh lemon into table salt and rub over the corroded area. Wash, rinse and dry carefully.
    Brass hearth and fire sets that have been neglected require special treatment. They can be rubbed with extra-fine steel wool (0000); however, this requires much time and work. Very fine emery cloth will give quicker results, but the metal must be rubbed in only one direction, do not use a circular motion. When clean, polish with a brass polish. Some commercial polishes do not require rinsing, so follow label directions. If this doesn't work, spray with black or brass colored paint in a pressurized can.

    How about a CA finish? 10 or 12 coats should work well... after first polishing, of course.

    Those of us that make duck calls deal with this pretty frequently since many/most calls use brass bands. I shine my brass using brasso polish on the lathe, then use spar urethane (either sprayed from a rattle can or dipped in a 50/50 mix of spar and mineral spirits). It is durable....Much, much moreso than laquer. It also builds a nice thick finish in two applications.

    After using brasso (a favorite in the military or use to be). I would think just about any finish would work if you are wanting to protect it.

    I'd give plexi a try a could thin coats should do it.
    Have a Nice Day!

    High class door hardware is usually finished and subjected to a vacuum to make it last. Probably a can of brasso along with the pen would be best.

    On IAP clear powder coating is the most popular way to keep the finish looking good on the brass part of cartridge pens.

    I am in the process of building an operational .22rf Gatling Gun. As you can imagine this gun is made of a lot of polished brass. After polishing I have found that Clear Powder Coating is best for perserving the finish.

    I have also found it to be the easiest and quickest finish to apply uniformly. Application is done using a Sears Eletrostatic Gun (Eastwood also works well) and a Wally World Toaster oven. Clear Coat is from eBay purchased by the pound.

    Powder Coat is so much easier than painting for metal that after you have tried it you will never pickup a raddle can again.

    Thanks for all the helpful hints guys. I ended up using CA just as I do on my wooden pens mainly because I already had it.

    Thanks Gary I will be checking into powder coating for future use. I have this same posting on the IAP sight and probably 95% of the recommendations are to use powder coating.

    Thanks again everyone.

    Permalac........This is what I use on my metal sculpture....It works very well. There are some other products on this page which may work well also.
