Wooster exclusive CT (Chemically tipped) polyester filaments are what give Silver Tip brushes their luster. These filaments have a full body feel yet they're very thin, flexible, and soft to virtually eliminated brushmarks. The responsiveness and bend recovery of these brushes are perfect for delivering sharp, single pass cuts. Silver Tip brushes provide excellent leveling and smoothing with all paints, but are especially suited for applying enamels to metal, varnish or polyurethane on wood, and thinner water-based coatings. Stainless Steel Ferrule. Hardwood handle.
