AK Gouache – Old Rust
A deeper, more muted rust tone for aged corrosion, dark oxidized metal, and long-term weathering—ideal for the shadow layer of rust effects.
 
What it does
Creates convincing old rust depth in recesses and around details
Adds “heavy age” to metal surfaces without looking orange and fresh
Works as the perfect base tone for layered rust (old → medium → fresh)
 
How to use
Apply in seams, recesses, around bolts, and where moisture would linger.
Blend outward with a damp brush to create stained corrosion zones.
Layer Medium/Fresh Rust on top to build a full rust gradient.
 
Best for
Corroded machinery, industrial terrain, ship/harbor vibes, chains, pipes, ruined metal props, heavy weathering.

ChalkyDot Tip
Rust tells a story: put Old Rust in recesses first, then add brighter rust only where flakes and edges catch light.
