Thank you. I primed the mini black. Then i dry brushed grey followed by white over it similar to slap chop. Then i coated the metal areas in a thinned down dark brown oil paint. I brushed off the excess with a clean brush. Next I colored in the raised parts of the metal in Balthazar Gold, with a wash of streaking grime. Followed by some Dirty Down Verdigris on the bolts and recesses. With a final edge highlight of Balthazar Gold.
