First off, I'm a newbee and don't work much with metal at all, but when I came across a blog entry here dealing with the patination of brass I knew that I'm at the right place!
I am in the process of building a reproduction of an old guitar and I need to age the metal parts so they look convincing.
I got some brass knobs with a chrome layer that I want to turn from shiny brand new to worn and weathered. If you check the photo you'll see just what I mean.
Now...how would you do it?
I already scruffed 'm up good so we can skip that part, but I wonder how to get the recesses dark and how I can selectively get some of the green grub in some areas and make it stay there?
I don't want to use them for decades before they look like that! ;-)
Any ideas and suggestions would be greatly appreciated!
