I’m thinking about getting a set of Kolinsky Sable paintbrushes for use in final detailing of paintings or for effects a standard airbrush cannot deliver. Because of their ancillary use, I’m not going to purchase a whole set of them, just numbers 3/0, 3, 5, and 8, since they tend to be the most commonly used for final detailing in airbrush art. Windsor & Newton Series 7 Kolinsky Sable brushes tend to be the gold standard, but I’m wondering if that might be overkill in this case as those are really designed for serious watercolor artists and command a premium price as well. Are there other recommended lines of Kolinsky sable brushes out there that perform very well but might not be quite to the standard of the Series 7 line? Also, these brushes would be used primarily with ComArt Airbrush paints. Are there any recommendations associated with care and cleaning of sable brushes when used with airbrush type paints?
