WOOSTER Exclusive CT™ (chemically tipped) polyester filaments are what give SILVER TIP brushes their luster. These filaments have a full-body feel yet they are very thin, flexible and soft to virtually eliminate brush marks. 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.
