Weathering is the act of distressing a model to give it a "used" look. This skill is crucial in Military miniaturism, as it adds a level or realism necessary to replicate a combat worn object or person. Weathering comes in many forms, as it simply refers to anything that gives the model a look of use. This can come in the form of streaking, rust, mud, and staining among other things. Oil paints are popular for these tasks, due to their long working time. Oils are also often diluted to washes to add a filter or depth to a model. Enamel streaking washes are also popular. Homemade weathering pigments (made from pastels, as well as marketed pigments, are used to create mud and rust effects. Many textured paints are also available to add body to weathering effects.
