Asphalt leaves its own kind of dirt, and this three-piece weathering set from AK Interactive's Cars and Civil Vehicles series is built around exactly that. Aimed at racing and road subjects — F1, Motorcycle World Race machines, or any street vehicles that need a few touches of reality — it pairs an acrylic splatter effect for flicked-on dirt with two pigments for city and asphalt-road grime. The medium of each item is printed on the box and in AK's own listing, and a user's guide is included. The two pigments are stocked by us separately, so replacing the one you reach for most does not mean buying the whole set again.
Set contains: AK8086 Dirt (Acrylic Splatter effects), AK145 City Dirt (Pigment) and AK146 Asphalt Road Dirt (Pigment)
Two kinds of product in one box: an acrylic splatter effect to flick dirt onto panels and running gear, and two pigments to build up city and asphalt-road grime
AK's instruction for both pigments, on each pigment's own page: apply them dry or wet as you prefer, mixing them with Pigment Fixer or White Spirit to apply them wet, or fixing them in place with either afterwards
City Dirt and Asphalt Road Dirt are stocked by us separately for top-ups; the Dirt splatter effect is not stocked separately

Notes · Q & A
What is a model wash and when would I use one?+
A wash is a very thin, highly pigmented acrylic fluid that flows into recessed detail by capillary action. Apply it over a sealed base coat to add shading around panel lines, rivets and surface texture, or use it as a full-surface filter to shift the overall tone of the model.
Do I need to seal the surface before applying a wash?+
A smooth, sealed surface gives the wash a consistent flow and makes cleanup easier. A coat of gloss or satin varnish before the wash prevents it from staining a matt base coat unevenly.
How do I apply a wash and clean up the excess?+
Load a soft brush and touch it to the area you want to shade; the wash will flow into the recesses on its own. After roughly 20 minutes of drying time, wipe away any unwanted residue from raised surfaces with a clean, slightly damp brush or cotton bud. These washes are water-based, so tools clean with water.
Can I apply a wash with an airbrush?+
Yes. The manufacturer confirms these washes can be applied by brush or airbrush. A light, even pass with an airbrush works well as an overall filter to unify the tone of a model or add a subtle colour shift across a large surface.
