Armor Recipe for Plague Marines, Terminators, Armor Panels on Death Guard Vehicles, and Mortarion. Utilizes an Air Brush

1. Prime the Model with a dark primer. For me, I air brush Black Vallejo Air Brush Primer.
2. Do another coverage of Dryad Bark over the whole Model.
3. Next, air brush using Death Guard Green but make sure the air brush doesn't break perpendicular. The goal of this step is to cover majority of the model but then have a darker undertone.
4. Again, air brush Elysian Green from above at a 45 degree angle.
5. Finally, air brush the highlighted points that stand out from above using Ogryn Camo
6. Edge highlight using Elysian Green on majority of the areas that are visible
7. Edge highlight the top points of the model using Ogryn Camo
8. To conclude your model (do this step after painting the whole model), using Streaking Grime to cover the whole model and let it rest for about 15 minutes.
9. After 15 minutes are up, use something like a eyeshadow brush in combination of AK White Spirit to gently wipe off Streaking Grime off the the majority of the model.
