Natural bristle paintbrushes work best with oil-based paints and finishes because the bristles don't absorb oils and lose their shape the way that they do with water.

Brush Care
Avoid dipping a dry brush into oil paint. For natural hair brushes, first, dip the brush into painting medium. This distributes the natural oils of the brush hairs and allows each hair to load properly with paint. Different levels of the painting require different types of brush hair.

So, to get oil-based ready to paint over, you need to take away a lot of that gloss.
