Vallejo Engine Grime 73.815 is an acrylic weathering effect for reproducing the greyish accumulation of dust, oil residue and dirt that builds up inside engine compartments and across mechanical surfaces. Wherever fuel and oil mix with airborne dust on a working vehicle, this grey-toned grime layer appears, and this formula recreates that specific look on scale models and dioramas.
Water-based acrylic, 40 ml pot
Apply directly on engine blocks, compartment interiors and mechanical surfaces
Dries rapidly; permits immediate further manipulation
Greyish tone replicates mixed dust, oil and fuel residue
Clean tools with water and soap

Notes · Q & A
What's the difference between a paint and a wash?+
Paints are opaque colour for coverage; washes are thin, pigmented fluids that flow into recesses to add shading and depth. Most painters use both.
Can I use these paints in an airbrush?+
Many acrylics can be thinned for airbrushing — check the product description; ranges marked "Air" or "airbrush-ready" work straight from the bottle.
Do I need a primer?+
Yes for bare plastic, resin or metal — primer gives paint a surface to grip and prevents chipping.
