In studying artists on youtube I found that many like to use oil paints on their acrylic paintings to brighten up and give more dimension. So I researched to find that no one says you cannot do it. Of course you cannot apply acrylic on an oil painted surface but applying oil in acrylic is a very common practice. It is possible to first cover the canvas with an acrylic painting, then add oil paint to portions of the canvas, the whole entire surface or just tiny details. Here it is so far.
