Pecos range of weathering powders can transform the appearance of track and models to give the effect of dirt, grime and brake dust residues settling around rails and track bed. They can also be used to weather rolling stock and buildings, toning-down freshly-painted surfaces to create a more realistic and natural look. Powders can be blended to create alternative colours and weathering effects.
Once applied weathering powder can either be left as-is, or sealed with a suitable matt varnish. Note sealing is recommended for models like trains which will need to be handled.
