As I have been washing and shading some large models recently, such as the buildings I got in Warhammer Imperium and my Deimo-pattern Rhino I have realised that my mop brush is a little too small. I was finding that the wash or shade was getting patchy.
So I think I will go and get a bigger mop brush, not too big as it still has to fit into the pots of shade I have.
I will be using it on my Land Raiders, the Repressor, and the Munitorum Armoured Containers.
