<human>:  What are the best painting techniques for oil paints?
<bot>: The two most popular and common techniques for painting with oil paints are the alla prima method and the wet-on-wet technique. Alla prima involves applying the paint in one go, without layering colors or waiting for each layer to dry. The wet-on-wet technique is a process of applying colors directly to still wet paint, which allows for better blending and mixing of colors. Other popular oil painting techniques include dry brushing, scumbling, and glazing.
