The Vallejo Model Wash Brown is a good wash that is created with special water based formula. It provides new techniques for rendering the process of ageing and exposure to the elements. It is formulated to bring the minute details of the model and accumulated dust caused by weather exposure. This wash is equally useful for quick shading for the creation of caked dust and dirt around the details of the model. The wash is also used as a filter, applied uniformly on the model to modify the base colour. It can be applied by brush or airbrush and dries very quickly.
