The AgentX Line Dressing is specifically formulated to enhance the performance of all modern fly lines. Treated lines will cast farther, remain clean longer and float higher than untreated lines. RIO's proprietary AgentX formulation features lubricants used in the new AgentX lines that will keep the line slick and clean longer than competitors' dressings. Easy to apply with a soft cloth. Allow 30 minutes or so to dry before buffing off.
