Vallejo is presenting a new range of water-based weathering effects like you’ve never seen before. Stay tuned!
The products will be introduced at the 2016 Nürnberg Messe.

The range includes:

Six references of textured thick mud, for real mud effects on models and dioramas.
Six references with several shades of light mud for splash effects.
Six references for dirt over engines, vehicles or dioramas.
Ten references for environment effects for natural and textured surfaces: rust, wet effects, snow and even crushed grass for vehicles!

See them all in Núrnberg or at your local dealer in January.!!
