Paint: VALLEJO Ammo DIO Drybrush Medium Rust - weathering pigment for miniature dioramas

VALLEJO Ammo DIO Drybrush Medium Rust is a specialized weathering paint developed for scale models, miniatures and diorama scenery. Supplied in a compact bottle with a formulation intended for drybrushing, this product produces medium rust tones that simulate corrosion on metallic surfaces, tracked wear and aged fittings. The texture is suitable for highlighting raised details and edges, delivering controlled, natural-looking rust effects without heavy dilution.

Advantages

The drybrush formula is balanced for easy pickup on a drybrush tool and controlled deposition on textured surfaces, allowing gradual build-up of color. It dries to a matte, stable finish that integrates with other acrylic modeling paints and weathering products. The compact bottle and brush-friendly consistency help reduce waste and maintain repeatable results across multiple touch-ups or model elements.

Suitable for

• Armor and military vehicles — creating tracked wear and panel edge corrosion
• Ship decks and metal structures — simulating salt and rust streaks
• Industrial scenery and buildings — aging pipes, beams and fittings
• Fantasy and sci-fi miniatures — detailing weathered armor and machinery

Key specifications

• Finish: matte rust tone suitable for weathering
• Application method: drybrushing and edge highlighting
• Compatibility: formulated to work with acrylic paints and common weathering pigments
• Container: compact bottle designed for model workshop use
• Coverage behavior: designed for buildable, layered application on textured surfaces

How to use

Work with a dry, low-pile brush: load a small amount of paint, then remove most of it on a paper towel until only a thin film remains on the bristles. Gently brush over raised details, edges and textured areas to deposit fine, rust-like highlights. Apply several light passes to build intensity gradually rather than a single heavy stroke. Allow each layer to dry before adding further weathering or sealing with a compatible matte varnish.

Usage recommendations

Test on a scrap piece or hidden area before applying to a finished model. For best results, combine with washes and pigments for depth, and use a matte sealer to protect the effect once satisfied with the coverage.
