This is the AK Interactive Weathering Plaster Base

A must have product for any modeler who wants to add volume to their mud and soil mixtures whether is for a diorama or to be splashed on to their vehicle. Mix the plaster in with any of our high quality Nature Effects line of different types of mud, earth, dust and soil. The combinations are endless. If your mixture is too thick you can dilute it with white spirit. If is too thin, add more plaster. Either paint your mixture on to your diorama or load a paint brush with your mixture and using your airbrush, blow short bursts of air at the brush to recreate splatters.
