Vallejo Engine Effects

Vallejo’s Engine Effects (part of their Weathering FX line) are realistic, acrylic-resin weathering solutions formulated to simulate engine oil stains, fuel spills, soot buildup, and general grime on vehicles and machinery. Featuring permanent pigments and water-based formulas, these effects allow modelers to depict operational wear with authenticity.

Designed for fast drying and easy layering, they can be manipulated immediately after application for streaking, blending, or buildup realism. Safe and non-flammable, Engine Effects detail adds atmospheric depth to mechanical areas with minimal effort.
