Modelling Pigment Vallejo Ammo Track Rust 35 ml – weathering pigment for scale models

VALLEJO Ammo Modelling Pigment Track Rust in a 35 ml bottle is a finely milled weathering pigment formulated for scale models and dioramas. The rust-colored powder is intended to reproduce realistic corrosion, oxidized metal surfaces, and accumulated grime on tracks, vehicle undercarriages, rail infrastructure and industrial elements. The pigment can be applied dry for subtle dusting, fixed with a dedicated pigment binder for permanent effects, or suspended in thinner for controlled streaking and wash-like effects.

Advantages

The pigment offers a consistent, finely divided particle size that adheres well when used with binders and thinners, allowing layered and graduated rust tones. Its color is tuned to represent natural iron oxidation and integrates easily with other weathering products for complex finishes. The 35 ml container provides sufficient volume for multiple projects while preserving the pigment’s quality during storage.

Suitable for

• Scale military and civilian vehicle models (tracks, wheel wells, undercarriage)
• Railway models, tracks and sleepers
• Industrial diorama elements such as pipes, tanks and metal structures
• Basework and scenic applications requiring rusty, dusty or corroded textures

Key specifications

• Form: finely milled dry pigment powder
• Color: rust / iron-oxidation tone
• Volume: 35 ml bottle
• Compatibility: works with pigment binders, thinners, solvents and dry-brushing techniques
• Application methods: dry dusting, fixing with binder, mixing with thinner for washes

How to use

Apply the powder sparingly with a soft brush for dry dusting to simulate light surface corrosion and accumulated dirt. For stronger, permanent effects, fix the pigment using a pigment binder specifically formulated for modelling or a matte varnish applied over the dusted area. To create streaking or wash-like rust runs, suspend a small amount of pigment in an appropriate thinner and apply with a fine brush, then blend as required. Always test adhesion and appearance on a scrap surface before treating final model areas.

Usage recommendations

Use incremental applications to build realistic depth: start with light dusting, then add fixed layers and final highlights. Store the bottle tightly closed in a dry place to prevent contamination and moisture ingress. When using binders or thinners, work in a well-ventilated area and follow manufacturer safety guidance.
