Paint: VALLEJO Ammo Oilbrusher Summer Soil 10 ml – oil-based weathering wash for scale models

VALLEJO Ammo Oilbrusher Summer Soil is a 10 ml oil-based weathering wash created for scale models and miniatures. Designed for brush application, this formulation produces realistic soil, dust and grime effects on model surfaces. It is suitable for use on plastics, resin and previously painted finishes to accentuate panel lines, recesses and surface texture while adding subtle tonal variation and an aged appearance to vehicles, figures and diorama elements.

Advantages

This oil-based wash offers controlled flow and extended working time, allowing fine adjustment of shading and streaking effects. The liquid is formulated to penetrate panel lines and recesses without rapidly evaporating, making it easier to manipulate with a brush after application. It blends smoothly with other oil-based products for layered weathering and can be softened or removed partially with compatible solvents to refine the result.

Suitable for

• Weathering and dirt effects on military and civilian model vehicles
• Enhancing panel lines, rivets and surface details on miniatures
• Adding subtle dust and soil textures in dioramas
• Blending with oil paints and other oil-based washes for layered finishes

How to use

Apply a small amount of the wash with a fine brush to panel lines, recesses or areas where soil and grime naturally accumulate. Allow the product to flow into details, then use a clean brush or absorbent cloth to remove excess and shape streaks or soft transitions while the wash is still workable. For deeper tones or layered effects, let the first layer dry partially and apply additional thin washes. Use mineral spirits or a dedicated oil thinner to clean brushes and to selectively soften or remove applied wash where necessary.

Recommendations for use

Work in a well-ventilated area and test the wash on a scrap surface or hidden area to confirm compatibility with underlying paint and varnish. Allow adequate drying time between oil-based layers and combine with other oil products for natural-looking weathering while avoiding water-based products until the oils are fully cured.
