A good wash is what makes busy engine detail actually read, and this one is mixed specifically for aircraft. Shake it and apply it straight over an acrylic-painted or varnished surface, and it flows into every recess to shade and define the mechanical clutter of a real engine bay.

Best for

• Shading engine and cowling detail on any aircraft
• Deepening recesses around cylinders, pipework and mounts
• Defining panel and mechanical detail before further weathering

Straight from the jar it drops into the detail and does the heavy lifting a five-minute job that turns a flat engine into one that looks like it actually runs.

35ml, ready to apply shake and go. Thin with white spirit or odourless thinner, and pair it with the rest of the AK Interactive Weathering Effects range for a finished engine bay.
