Slime Grime Light 73823 Weathering FX Vallejo

Vallejo Weathering FX Slime Grime Light 73823 is a water-based acrylic product designed to reproduce light damp grime on recent or lightly stained terrain in scale modelling, miniatures and scenery work. It helps blend wear with the base colour without having to prepare complex mixes from scratch.

It can be applied locally with a brush to control stains, splashes and buildup, or combined with other weathering layers to reinforce realism on wheels, underbodies, bases, damp roads and muddy terrain. Work in thin coats for a subtle result and only build up product where dirt, damp or wear would realistically settle.

The Vallejo Weathering FX range is solvent-free and comes in a 40 ml jar. It’s a practical way to add environmental effects to vehicles, bases and dioramas, especially when you want a controlled, repeatable finish.
