Silver Tip paint brushes from Wooster have chemically tipped polyester filaments that are feather-soft—a feature that virtually eliminates brush marks—but they also have great bend recovery for creating precise single-pass cuts. Silver Tip brushes can be used with all paints, but they are especially suited for applying enamels to metal, varnish or polyurethane on wood, and other thin, water-based coatings, like stains.
