my open gun is in the white, but I clean it and lube it so it doesn't rust. When that is done I take a buffing wheel with some Mother's Chrome car polish and polish the slide, most people think its a chrome gun. It will be soon I was waiting for the season to be over before sending it out. I would use a patch with the polish on it, on a small spot on the gun, to see how it works. Don't use the buffing wheel till you know the finish can take it.
