Neutral Earth allows the modeler to create their 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 tones. This is a high quality acrylic product developed for extreme realism. Stir well, slowly adding in small amounts of your color until the desired tone is achieved. Perfect results are obtained by working in thin or thick layers. If desired this gel can be diluted with water or an acrylic thinner resulting in improved flow over the surface.
