Monroe Models Weathering Powder Mini Starter Sets are convenient groupings of self-adhering pigments that are great for making your models look weatherbeaten for added realism. Easily applied using a brush, they're self-adhering so they won't rub off like chalks. Choose from a variety of weathering colors to make your locos, cars and structures look dirty, rusty and dusty! Each Weathering Powder Mini Starter Set includes four 1/4oz 7.4cm containers each in a different color.
