Vallejo Mecha Color - Fuel Stains (Gloss)

The glossy grime that tells a story. Vallejo's Mecha Color Fuel Stains is a gloss weathering colour for mecha, gunpla and vehicles — built to streak fuel spills, oil leaks and wet grime down from caps, seams and hatches. Its glossy finish reads convincingly as fresh, wet residue on hard-worked hardware.

Best for

• Extra-resistant acrylic formula
• Fuel spills, oil leaks and wet grime on mecha and vehicles
• Streaking down from fuel caps, seams and hatches
• Brush for targeted stains, or airbrush for soft build-up

The gloss finish is the trick — it makes the stain look genuinely wet rather than just painted on.

The wet-look grime for hard-worked machines. Pair it with a matt varnish elsewhere so the fuel stains stand out.
