I have decided to rework Cthonian to better match the current army.
After the paint job I gave it a light coat of Glosscote and busted out the Burnt Umber Oil paint for a pin wash around crevasses and rivets.
I then used a hair drier to speed the drying waiting until the thinner I used for the wash to evaporate.
I then used a Large brush slightly damp with thinner and created downward streaks on the sides and along the top I went with direction of movement front to rear.
Now it dries for 2 days while it all sets in.
