Pioneer is a go-to brand for Adickes. The pro specifically likes Pioneer Spirit Window Rechampir, a round brush ideal for precision painting that comes in 15 to 32mm sizes. He has found that these brushes make cutting-in tops of base boards and other curved surfaces such as raised panel doors easier for homeowners he coaches.

The Summit Precision brush is another Pioneer option that works well for low VOC paints with their faster dry times and less flowing and levelling.
