"Gold"? none, I'm guessing. Lots of polishing compound to get the brass nice and shiny and(hopefully) some clear lacquer to keep it that way.
At just a little over $100, I think it's a better price than most of the awful repaints. And no fake Nazi crap on it that I could see from the pictures.
I could see this camera being kind of fun--imagine the look on Oleg's face when he opens the package after you send it to him for a CLA...😀
