I started with a nice coat of Necron Abyss foundation.
Then I added a heavy dry brushing of Mordian Blue.
Then I finished them with a light drybrushing of Bleached Bone over the crests of the waves.
I am not sure if I will use a mat varnish to seal them or not but right now I think that I will be adding that to all of them in the morning. Not sure if I will be tackling the ships or the accessories next but I will post pics and let you know what I did when I get it done.
