Of course! I used rattle cans to prime in matt black, and then build a pretty harsh zenithal highlight in white. I then drybrushed a couple of layers of citadel's runefang steel. I then picked out the details in citadel's gold Retribution Armour, before highlight both the steel and gold with more runefang. I then painted a no-brand black india ink into the recesses that had got any paint from the zenithal or drybrushing, just to tidy things up. I then ended up with a very shiny robot, and started to take it back with some diluted Strong Tone from The Army Painter - a couple of coats of that. Last of all the real grease maker! I finish it by picking out individual places to wash with some acrylic ink - It's a light blue green called cobalt by windsor and newton, and over the dark metals it greats that oily kind of sheen. Last of all, a coat of matte varnish.
Enjoy!
