What it is
Hareline Zap CA Super Thin is a quick-drying fly tying adhesive with a very thin viscosity. It wicks into small gaps and thread wraps, then sets up with a strong, durable bond. Because it’s so thin, it’s well-suited to precise application when you don’t want a bulky glue line.
What to tie with it
Use it to secure tying materials right where they meet the hook shank, especially when you’re locking down slick or stiff materials under thread tension. It’s also handy for bonding small fly parts and doing intricate pattern tying where a thicker adhesive would fill in detail or add unwanted bulk.
Flies and the fish they're for
This kind of super-thin CA gets used across categories rather than belonging to one “signature” pattern: anywhere a fly has small parts that need to stay put, it’s in play. On trout flies it’s commonly used to lock down delicate components on small nymphs and dries; on bass and saltwater flies it helps keep durability high on streamers that get chewed, like baitfish patterns for smallmouth, stripers, and redfish. It’s also a go-to when you need a bond without building a head or changing the profile, which matters on everything from trout bugs to coastal patterns.
