Liquid Clear is one of three Bob Ross Liquid Basecoats essential to the Bob Ross Wet-on-Wet Technique®. Liquid Clear is a particularly exciting ingredient for wet-on-wet painting. Like Liquid White/Black, it creates the necessary smooth and slippery surface. Additionally, Liquid Clear has the advantage of not diluting the intensity of other colors, especially the darks which are so important in painting seascapes. 237ml.
