Artist Notes
I started with a spray of Vallejo Grey. Then I painted the treads, vents, and front of the missile launchers with Leadbelcher. After that I washed the mini with Nuln Oil. When the wash was dry, I painted the panels with Ulthuan Grey and brightened the metal on the launcher with some more Leadbelcher. I did the checkers with Altdorf Guard Blue. Then I finished with some highlighting with White Scar. All of those paints other than the Vallejo spray are from Games Workshop.
