Dust and Dirt Deposits The faithful recreation of accumulated dust and dirt is one of the key factors of realistic weathering. This newly designed weathering set brings a brand new formula of specialized key ingredients, giving you the most common tones of accumulated dirt and dust. There is no longer a need to experiment and try to prepare your own mixtures in order to reproduce these effects, because we have found the answer for you. Our enamel paints can be applied straight from the bottle or diluted, onto the chosen areas of your model. Once they are dry, they have the same scale appearance as real dust and dirt.
