Secret Weapon Weathering Pigment - Exhaust Black can be used to create realistic exhaust and carbon deposits on tanks, infantry, scenery and terrain and can also be used to create washes or to add additional pigment to your acrylic paints.

The technique is as simple as adding a bit of pigment to a brush, or even your fingertip, and gently rubbing it over the area that you'd like to weather.

Each bottle contains approximately (20ml) of pigment.
