Terrain texture. Neutral earth texture allows the modeler to create his own earth tones; it is a neutral white that can be colored with acrylics for use on diorama or vignette bases allowing for a wider range of shades. This is a high quality acrylic product developed by extreme realism. Mix well, slowly adding small amounts of your color until you get the desired shade. Perfect results are obtained by working in thin or thick layers. If desired, this gel can be diluted with water or an acrylic diluent resulting in improved flow over the surface. Not toxic .
