Gehrke’s PZ Fly-Line Dressing enhances fly line performance by improving control and enabling longer, effortless casts. When applied to both the fly line and leader, it restores floatation even to lines with cracked, brittle coatings—extending their usability until replacement is possible. While it doesn’t repair damage, PZ Fly-Line Cleaner & Conditioner preserves line integrity by preventing water from reaching the core, making it an essential maintenance product for serious fly fishermen.
