With an airbrush, spray an all over zenethal highlight of Duraluminum downwards at a 45 degree angle.
Spray White Aluminum almost straight downward, from the top of the model. Be selective only catching the very top, face and shoulders.
Now we do an oil wash on all of the Necron and the weapon coil. I poured out the amount odourless Artists' White Spirits I felt I needed for the wash and added paint to it, until I was happy with the consistency. I used 3 parts Ivory Black, with 1.5 parts Burnt Sienna and 1 part Cobalt Violet Hue, all from the Winton range of oil paints.
After giving the oil paint at least an hour to dry, wipe paint from the exposed areas and avoid recesses. I like to use makeup sponges or those little sponges on stick for applying makeup. If you want to remove the paint extra thoroughly in an area, add a very small amount of white odourless Artists' White Spirits to the sponge.
Selectively highlight exposed edges and places where the light would hit with Silver RLM01 Metallic .

Finally, highlight more selectively with pure Silver .
