I’m battling with bronchitis, so I had a bit more of a chance to make progress on the Grey Knights than I expected. (In between sleeping and coughing up large quantities of neon gunk)
Let me just say straight out of the gate just how amazing the Metal Color range from Vallejo is. These are without a doubt the best metallic paints I’ve ever used. They apply so smooth, and don’t look like glorified glitter paint like some ranges. In the hands of someone more skilled than me, I believe they could look like the model was actually made of metal.
The pictures above are the base coat of Burnt Iron, over the gloss black primer. I applied the paint mostly from the bottom-up, so I could be sure of hitting the recesses. The gloss primer really helps the metallic paint shine, so the finish was a little brighter than I was expecting, when held under the painting lamp.
