The flatbed of my Ork Halftrakk was sprayed with a Humbrol brown paint. I then gave it a wash of Devlan Mud. Not sure if I like using this wash over the usual brown ink and paint wash I usually use. I usually use a wash consisting of brown ink, paint and water.
I added some more washes to the body of the Half Trakk using Devlan Brown and Badab Black.
Next stage will be a drybrush.
