I have had a Mark IV Forge World Grey Knights Dreadnought on my workbench for a while. After getting some weapon arms for the model. I gave the main model a black undercoat and started base coating with a metallic paint. The weapons I had given a white undercoat. Getting it out from storage, I decided to almost start again and gave the model a base spray of Leadbelcher. I gave the model a wash of Nuln Oil Shade. For the next stage I used some Citadel Leadbelcher. I took a large brush and gave the model, what I would call, a heavy drybrush.
I followed this up with some lighter drybrushing, first with Base Grey Knights Steel, then Layer Ironbreaker and finally Layer Stormhost Silver.
The aim was to add brightness to the Dreadnought.
