AK Interactive Watercolor Pencil Streaking Dirt (AK10030)

Streaking Dirt is the AK Interactive watercolour pencil for grimy runs — the kind of vertical staining you get below hatches, vents and anywhere dirt has been dripping and drying for months. Because it's water-soluble, you get pencil-sharp control going on, then all the softness of a wash once you introduce a wet brush.

How to use

• Draw fine lines down from bolts, seams and raised detail
• Drag the colour out with a clean, damp brush
• Works over primed or painted models, vehicles and terrain

Two minutes with this pencil and a wet brush turns a clean paint job into something that's clearly done a tour of duty.
