From the Weathering Effects line from Vallejo, Rain Marks helps realistically model how rain carries dust and dirt over surfaces, leaving streaks on vehicles and other objects. Dust, displaced by humidity, accumulates in the joints and chinks of the model.
This can be applied directly on the base, dries rapidly, and permits immediate further manipulation. Tools can be cleaned with water and soap.
Each comes in a 40ml/1.35 fl oz pot.
