Or you can do what I did after my paint wore off. Take it apart and repaint all the gold pieces using Metallic Acrylic enamel gold spray paint by Plasti-Kote in the rattle can that you can buy at Wally World. Just make sure you get a sealer for it. I forgot to and as you can see the paint has sorta come off on the main gold button.
I plan to hunt down another Mace saber and once I buy it I'll do the same thing to it. Trust me though it does look much better than the ugly shiny gold that MR
did for the saber.
Here's a couple of pictures of the saber and one of the can itself.
Edit: It's easy to take the saber apart, even the gold buttons. All though the gold buttons you may have to glue back on using super glue.
