I recently got a SKB O/U that has a "silver nitride" finish on the steel. Never had any experience with this type of finish and can't find any info, it's begining to freckle/speckle. Can this be refinished to silver nitride, polished/buffed, maybe blued ??, etc., is it any good ? (I don't think I like it) but I can be convienced otherwise. Thanks for any knowlegeable input. [;)]

    I like Happish semichrome polish. Not sure I'd use it in this case.

    Other uses of the term

    The name "silver nitride" is sometimes also used to describe a reflective coating consisting of alternating thin layers of silver metal and silicon nitride. This material is not explosive, and is not a true silver nitride. It is used to coat mirrors and shotguns.[6][7]

    I'm sure it could be removed and the gun re-blued or whatever new finish installed but I'd bet it will cost more than the gun.

    I would not use any steel wool or polish.Like all gun finish they need preventive maintenance yours is already damaged so now the most important thing is to do NO FURTHER HARM Get a can of Kroil "they sell it direct if you ca't find locally" wrap the action with a paper towel and wet the towel with kroil let stand for 24 hours + and then remove towel and scrub the finish with burlap then coat the receiver with paste wax let dry and buff. Your finish is not stainless steel oil and paste wax is YOUR FRIEND. a good oil is Ballistol it will not harm metal wood or leather . it is also non toxic.

    [B)] I failed to mention I have used Kroil & burlap with no results of improvement nor damage, just what is this stuff "silver nitride", it looks kinda like a matte stainless steel ??? can it be removed and then blued ? I could live with a nice blue job but answers are hard to find. I am bewildered [:I]

    any engraving will be rounded and IMHO look horrible if buffed same with bead blasting unless done with something like baking soda.There are a number of high end shotguns that use this finish I would contact Doug Turnbull He does top notch gun refinishing He might be able to Case color your SKB french grey is another very good looking finish. Again any DIY trial will result in more damage then what you currently have.and make a problem worst. One reason the original seller more then likely priced the gun the way he did was because of the damage to the finish.
