Dirty fishing line can dramatically impact the distance and accuracy of your casts. Line & Lure Conditioner keeps your fishing line (both braid and mono) in excellent condition, protecting it from harmful UV rays that can deteriorate your line over time, and also provides a protective barrier against slime, dirt and salt build-up. It also reduces the 'memory' in monofilament line. Simply apply Line & Lure Conditioner when you're spooling up and use it frequently while you're on the water. It's great for keeping your lures and reels in good shape too. Kevin Van Dam's Freshwater Formula comes in a 4 oz bottle, and the Saltwater Formula comes in an 8 oz bottle.
