Photo stores carry specially designed anti-static brushes for 
darkroom work. They are made with very soft, fine-haired bristles 
and have some sort of ionizing insert (polonium?) built into them. 
You may find that they work better than ordinary paint brushes. 
IIRC, they're not particularly expensive.
