This is a very heavy bodied thick gel which can be placed on the palette and mixed with the paint by picking up with a brush or palette knife and it works in just as easily as mixing a paint colour. The surface finish matches the satin finish of the paint.
Artists who would like to have a more oil paint like texture, using palette knife or brush for increased contrast and painterliness will like this medium because it is so easy to mix in.
