The Gunpowder Line consists of colored weathering pigment powders that can be applied onto the model dry to obtain dust effects for example. Both water and enamel thinner can also be used to spread the pigments in order to obtain different effects while also fixing them to the model.
Gunpowder pigments can also be built up in layers to represent thick layers of mud or rust. It is recommended that you use FX-01 Fixer when doing so. These powders can also be mixed with other paints like acrylics and enamels in order to alter the tone or to obtain thick textured earth and rust effects. You can obtain the most realistic results when using different rust or earth tones together.
A semi-matt tone that can be used to create authentic looking freshly manufactured guns or other dark metal surfaces for example.
