Cobra Glazing Medium is a colourless medium that can be mixed with Cobra oil paint to make your paint flow better. The added amount affects the degree of transparency. This technique - making coloured transparent paint layers without a visible brush stroke - is referred to as glazing. Glazing mediums are very fat and should only be applied in the final layers of a painting. This medium is based on vegetable oils. Properties: · Increases the gloss and transparency of the paint · Can be thinned with water · Makes the brush stroke run slightly · Does not influence the drying time of the paint · Increases the durability of the paint film · Yellows slightly
