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 then did a lighter drybrush of various silver paints.
I did intend to paint the base for the model next, but upon checking the workbench feature for my Grey Knights, I realised that I needed a paint I didn’t have. For my Grey Knights I painted the flocked (well sanded) bases with Bestial Brown and then drybrushed with Bleached Bone. After that I went over the edge of the slottabase again with Bestial Brown.
I don’t have a pot of Bestial Brown, and Citadel no longer manufacture that colour. According to the Dakka Dakka paint compatibility chart the best option is Mournfang Brown. Might have to pop out and buy a pot of that.
I did though paint the paper for the purity seals on the Dreadnought using Layer Ushabti Bone. I also used Bronze and Gold Sharpie pens for some of the metallic aspects of the model.
