There are several paint applications where the paint can be used as a primer, and this is called a self-priming paint. In addition, many paints are marketed as a paint and primer in one, however, that refers to its ability to adhere well to a surface and to cover the previous coat. In more difficult priming situations, like staining or painting with a very dark color over a light color, it's recommended to use a dedicated primer followed by a top coat.

In the past oil paints referred to either petroleum based paints or linseed based paints. Today in the USA petroleum based paints are no longer sold and it is difficult to find linseed based paints though they do exist with a small proportion of linseed oil. Alkyd paints are made with synthetic oil and are readily available and have come to be known as "oil" paint.
