OHP is on to something, or on something, I'm not sure..
Put one of the rust-ification processes you have seen to work on those bars and they would fit right in! If it was me, I might try the tan primer paint and blow torch method....can't remember who posted it, but a cool effect. Maybe mix a tiny bit of flat black in to get a darker color rust....Or for quick and fast with steady results, the OddJob method and tool of choice....
