parkerizing

timhill100
Can anyone reccomend a gunsmith or company that does parkerizing, preferably in TX? I have an old 870 that I'd like to get done. Thanks.

    I am getting ready to re-do my mosin. I want to parkerize it and have the kit to do it.

    I have 2 questions.

    1. Do I need to remove all the blueing?

    2. Do I have to protect the inside of the barrel, and what would be the best way to protect the inside if I do?

    Thanks for the help.[:D]

    Probably be harder to see.
    They sandblasted the gun before the Parkerizing treatment, which dulled the markings. The only way to get Parkerizing off is even more abrasive attack by blasting or sanding, which will blur the markings even more. A serious restoration shop would re-engrave the markings but that is getting into serious expense.

    I did not know about the Iosso product. If it works as advertised, it will leave you in position to judge the condition and know how to get to blue. There was a guy on another board who reported removing rust FROM Parkerizing with Evaporust, so I don't see how it will remove Parkerizing.

    There won't be any other finish "under" the Parkerizing. The gun was sandblasted to bare steel before it went in the phosphatizing tank.

    This is complicated.

    Usually parkerizing is removed with abrasion (eg bead blasting), and as Hawk said, doing that is probably going to make underlying marks worse, not better.

    But it is *possible* to remove parkerizing (eg phosphate finish) chemically. EG:

    http://www.orisonmarketing.com/corrosion/evaporust/evapo-rust.html

    http://www.iosso.com/MivaStore/merchant.mvc?Screen=PROD&Store_Code=A&Product_Code=00018&Category_Code=GunCleaning

    Also supposedly pure phosphoric acid, or phosphoric acid containing products (eg naval jelly) can loosen up the parkerized coating, making it possible to remove it with relatively mild abrasion (eg steel wool).

    So *MAYBE* if you removed it that way, you could bring out the marks a bit more, depending on how well preserved they are.

    If you want to try this, I'd be careful to watch the process very carefully (and/or use a diluted stripper) so that you don't etch the underlying metal or take off the marks you want to preserve.

    Unfortunately, there is no guarantee whatever that there is any sort of finish underneath the Parkerizing, and more likely than not any method you used to remove it would also remove the underlying finish too.

    So you'd have to then refinish the gun, adding effort and expense.

    Unless these markings were EXTREMELY special to you (eg its some kind of heirloom), its probably not worth the effort or expense to try this.
