[Unclenick]

Your phone's auto-spell correction is messing with you. A "finish" is a coating, while "Finnish" are people from Finland. I hate those automatic correctors in Android and constantly have to go back and replace what it has decided, incorrectly, is what I meant to write.

A flaking or peeling finish is usually a sign of inadequate metal preparation for the finish. If it confines itself to inside the bolt, you are probably fine, as that can't be seen when the gun is assembled and in most guns is meant to be an unfinished area so the bolt operates freely and smoothly (though I don't know your particular gun).
