With the base colors complete, I dry brushed the metal areas using vallejo gunmetal. It's a little bright, but will be knocked back when I apply an oil wash later on. I then dry brushed the base using the two colors, and a mix of white. I also weathered the model by dabbing cold grey along the edges and corners to mimic paint chipping. Lastly, I lightly airbrushed vallejo beasty brown on the feet.
I applied decals on the model by first using GW 'ardcoat to create a gloss finish where the decal would be placed. This creates a smooth, even surface for the decal to adhere to, and prevents "silvering" or bubbling of the decal. It looks strange to see a gloss area on the model, but once the satin varnish is applied over the entire model, the decal blends perfectly.
Once I covered the entire model using vallejo airbrush satin varnish, I prepared an oil wash. I do this by combining a small amount of oil paint with mineral spirits or turpenoid thinner. The wash should have a thin, milky consistency.
Here you can see what a difference the wash makes. It fills smoothly and easily into the panel lines and details of the model thanks to the satin varnish. A little smudging is fine, as it can be easily wiped away an hour later, leaving the details in the crevices.
And here's the finished model! Our battle worn and experienced commander strides confidently onto the battlefield. Quite a difference from the package ready, 'flinching away in fear" pose the model started with. I've only to finish the included weapons options, and he'll be ready to field.
