So all the metal gets a rough base coat of 50/50 Tinbitz/Leadbletcher. The the workshop's credit, boltgun metal's replacement, mixes much better than boltgun ever used to.
All the decorative trim around the panels on the armour I just a gave a basecoat of Tinbitz.After this It all got a solid black wash, mixed from just acrylic black with water.
Once the wash had dried(I left it overnight), I grabbed a sponge and sponges tinbitz and boltgun mix lightly over the metal. I followed this with a pure almost 'Sponge drybrush' just to highlight and catch the edges of the metal.
So after the basecoat was down, I mixed a little bleached bone with the charadon granite, and begun highlighting with my trusty sponge. I only gave the plates two highlights, as the details will come from multiple layers of washes and weathering at a later stage.
Speaking of which, The legs got their first wash now, Gw's seraphim sepia. I used a standard brush to apply this in certain nooks and crannies on both the metals and the granite armour. In places I dragged it down, to give the impression of running oils and stains, as can be seen on his big toe here.
Once this has dried, I gave it a test with the torso. This shot shows him next to his big brother. Together they'll rule the galaxy I tell you.
