Paint, VALLEJO Vallejo Ammo DIO Drybrush Light Rust – acrylic drybrush paint for models and dioramas

VALLEJO Ammo DIO Drybrush Light Rust is an acrylic drybrush paint formulated for adding subtle rust highlights and aged metallic effects to scale models, miniatures and dioramas. The consistency and pigment load are tuned for drybrushing: the paint deposits thin, controlled layers on raised details, edges and textured surfaces without obscuring fine sculpting. Its light rust tone integrates with metallic bases, weathering washes and terrain materials to recreate corroded surfaces and natural wear.

Advantages

The acrylic formula dries quickly, allows for gradual build-up of colour and cleans up with water. Designed specifically for drybrushing, this paint spreads thinly across textured areas to emphasize relief and simulate light corrosion. It is compatible with standard modelling primers and acrylic basecoats and works well over metallic paints and weathering products to achieve convincing rust effects.

Suitable for

• Scale model kits (armour, vehicles, ships)
• Military and historical miniatures
• Diorama scenery and terrain textures
• Weapons, tools and mechanical details on models
• Highlighting raised edges and surface texture

Key specifications

• Type: acrylic drybrush paint
• Finish: matte to semi-matte rust tone suitable for weathering
• Application method: drybrushing with a soft or dedicated drybrush
• Drying: quick-drying water-based formulation
• Compatibility: designed for use over acrylic primers, basecoats and metallics

How to use

Apply on a previously primed and base-coated surface. Remove most of the paint from the brush on a palette or cloth until only a minimal amount remains, then lightly stroke across raised details and edges to deposit thin, controlled layers of light rust. Build intensity gradually by repeating short passes rather than applying heavy coats. Allow the paint to dry between layers and clean brushes with water before the paint fully hardens.

Usage recommendations

For best results, combine Drybrush Light Rust with metallic basecoats and darker rust or wash tones to create depth. Use soft-bristled brushes and practise pressure control to avoid over-application. Store in a cool, dry place and reseal the cap tightly to maintain consistency.
