I am not sure if that's even the right name for it, but an old friend of mine way back in middle school used to paint little metal Warhammer figurines and he'd always finish them by painting this "antiquing wash" over it to make it black, then wiping it off to leave a sorta tarnished weathered look. I was at three different places and the closest I could find was a wood varnish thing. Anyone have any idea what I am talking about or where to look?
