Just apply it with a brush or simply dip your base coated miniatures, shake, and you are almost done.
Made from very thin black pigment the Army Painter Quickshade Dark Tone has proved a hit with evil armies of miniatures and models which require a sharp contrast in colours and shading.
 
It is brilliant for grey, blue and all types of armour for instance. For that superior overall look of an army made for wargaming, you would be hard pressed to beat Quickshade Dark Tone.
