Mr. Weathering Liner is a new style of weathering paint material in a pencil form which is easy to use. You can use it not only on a plastic surface but also on glass surfaces. If you rub the applied color with a cotton bud an authentic smudged texture can be created. It can be used not only for weathering but also for the effects necessary in scene model painting including handwritten letters. This set includes PL01 Rust Red, PL02 Rust Orange, and PL03 Soot Black.
