Corona Suave 11038 China Bristle and Ox-Ear Hair Blend Paint Brush

Brush paints a fine coat. Only issue is a few bristles loosen and fall out on the surface. What can I do to stop this.

Finally!

Been searching for a natural hair brush for applying oil based polyurethane. This was my fourth try (including china hair purdy) and it was perfect! Soft, cleans like new with mineral spirits. Gave used / clean a half dozen times. It Will occasionally shed so I recommend one inspects for wayward hairs before each use.
