How do you finish, barrels,sights, recievers,bare metal etc..
Do you finsh them before the trunion is pressed on or after?
Do you finish the parts first, then assemble?

Do you use gun blue?
All help would be appreciated.

    Sir it would help to know WHAT make and model GUN you are asking about . Most fire-arms don't have trunions[?] as to bluing Most fire-arms the metal is polished and then Blued BEFORE the parts are assembled. Bluing salts ETC need to be flushed off to stop the process.

    On an AK you probably don't want to blue it! Blueing refers to a typically lusterous SHINY blue-black appearance. Military style rifles are typically parkerized (blackish-grey and non-reflective).
    There is a huge amount of gunsmiths and companies that do it. If you live in a smaller town your choice is to "by legal method" ship it to someone who parkerizes or there are a lot of do-it-yourself kits out from companies like Brownells.com and many others.

    Do a couple of web searches on "gun finishing" and "parkerizing".

    finish all the parts before assembly.
    take a look at duracoat finishes for a "do it yourself" option for the reciever etc.

    You finish the parts before assembling them.

    If you assemble them first, then the areas where the parts touch each other won't get finished, sort of defeating the whole point of the exercise. Also, as mentioned, once the gun is assembled its much harder to wash out the chemicals used for the finish.

    While not that complicated, gun bluing involves immersing the gun parts in a high temperature bath of potentially caustic chemicals. While this *can* be done at home, its one of those things that might be best left to the pros.

    There are various "cold" blue products that will approximate the appearance of a "hot" (ie REAL) blue finish, but none of these are particularly durable, and in general, they are best considered a cosmetic touch-up rather than a true functional gun finish.

    As already mentioned, parkerizing is a more durable finish (though a somewhat less cosmetically attractive one), and this is more readily doable as a home "stovetop" type procedure.

    There is a lot of stuff on the internet about how to do this. Google is your friend.

    Thanks everyone, I am going to order a parkerizing kit.
    Please let me know if there are any details that the instructions leave out, by experience.
