AK Weathering Pencil – Streaking Dirt (AK10025)
A dirt tone made for vertical grime streaks, rain marks, and dragged-down dust on armor panels, vehicles, and scenery. The Streaking Dirt Weathering Pencil gives you precision placement like a pencil, with the ability to blend and shape the streaks using water for a natural, worn finish.
 
What it does
Creates realistic rain streaks and grime trails from bolts, rivets, and panel lines

How to use
Mark small lines under details (bolts, vents, edges) on a matte surface.
Pull downward with a slightly damp brush to form the streak.

ChalkyDot Tip
Make streaks look real by keeping them uneven: some short, some long, and leave a few almost invisible—nature never repeats the same line.
