Thank god the British wore throusers and jackets of the same colour. That gave me the chance to apply Vallejo British Uniform by airbrush. In less than half an hour the ten soldiers coated and the airbrush was cleaned. Next time I'll use more slender handles. These are nice to grip but too large to spray from below to get the downside of the figures covered.
Next I let the miniatures dry and started to paint the other colours the very next evening.
