All the brushes (3 in x 4.5 in) you need to get started. This money saving three brush kit contains:
A brass brush (10 mm) for renewing base structure, opening pores before you wax (for this step brush in the opposite direction - tail to tip), and brushing hard waxes.
A nylon brush (10 mm) that is the workhorse of wax removal. Designed to be stiff enough to remove wax in less passes to save you time.
A soft, fine horsehair brush (8 mm) for removing wax from the fine structure of your base for the ultimate polish!
