Hey Banderso, welcome to the O-Review! In reference to your issue about the FMJ frame that you scratched slightly, there isn't much you can do take those scratches out from what I know. The FMJ has always been a very "sensitive" material in the sense that it scratches easy and flakes even easier.
I have however heard of places out there that will indeed dip or refinish a frame for you. I am not sure of getting the exact FMJ look that you have, but I have seen a lot of work from Dr. Chop and he does some pretty amazing things, including the FMJ look. If I were you I would try to reach out to him possibly and see if there is anything he may be able to help with.
is his site and there is a contact section on there.
Good luck with it and I hope that helps a little bit.
