# **Kylebooker HARD AS HULL HEAD CEMENT – Fly Tying Original, Penetrator, Thinner Hareline NEW! – Is It Worth the Money?**
As an avid fly fisherman, I’m always on the lookout for high-quality tying materials that can improve my flies’ durability and performance. Recently, I came across the **Kylebooker HARD AS HULL HEAD CEMENT** in three variants: **Original, Penetrator, and Thinner Hareline NEW!** This product claims to be a game-changer for fly tying, but does it live up to the hype? Let’s break down its features, performance, and overall value for money.
## **What Is Kylebooker HARD AS HULL HEAD CEMENT?**
This specialized head cement is designed to strengthen and protect the heads of flies, particularly those used in saltwater or heavy freshwater fishing where durability is key. The product comes in three formulations:
1. **Original** – A standard, high-strength head cement that dries hard and glossy.
2. **Penetrator** – A thinner formula that seeps into thread wraps for deeper reinforcement.
3. **Thinner Hareline NEW!** – A lighter version for delicate flies where flexibility is needed.
## **Performance & Durability**
One of the biggest selling points of **HARD AS HULL** is its **rock-solid finish**. Unlike some head cements that remain slightly tacky or peel off over time, this product dries completely hard, almost like a resin. This makes it ideal for flies that endure aggressive strikes or abrasive environments.
– **Saltwater Flies** – The **Original** formula excels here, preventing unraveling even after multiple catches.
– **Thread Reinforcement** – The **Penetrator** version works wonders on tightly wrapped thread, locking everything in place.
– **Delicate Patterns** – The **Thinner Hareline** is perfect for small dry flies or nymphs, where flexibility is crucial.
## **Ease of Application**
Applying head cement can be tricky—too thick, and it clumps; too thin, and it doesn’t provide enough protection. **Kylebooker’s formulas strike a good balance**:
– The **Original** has a medium viscosity, allowing smooth application with a brush or needle.
– The **Penetrator** flows easily into thread wraps without excessive buildup.
– The **Thinner Hareline** is excellent for quick, even coats on small flies.
## **Drying Time & Finish**
Drying time is reasonable—about **5-10 minutes** for a full cure, depending on humidity. The finish is **glossy and hard**, giving flies a professional look while adding structural integrity. Unlike some cheaper cements, this doesn’t yellow or crack over time.
## **Price & Value for Money**
At around **$8-$12 per bottle**, depending on the variant, **HARD AS HULL** is slightly pricier than standard head cements. However, considering its **durability and versatility**, it’s a worthwhile investment for serious fly tyers. A little goes a long way, so a single bottle lasts for dozens (if not hundreds) of flies.
## **Final Verdict: Is It Worth Buying?**
**Yes!** If you tie flies that need extra durability—especially saltwater patterns, streamers, or heavy nymphs—this product is a **fantastic choice**. The **Penetrator** version is particularly useful for reinforcing thread wraps, while the **Thinner Hareline** is great for delicate applications.
While it’s not the cheapest option on the market, the **performance and longevity** justify the price. For anglers who want **reliable, long-lasting flies**, **Kylebooker HARD AS HULL HEAD CEMENT** is a **top-tier choice**.
Would I recommend it? **Absolutely—especially if you’re tired of flies falling apart after a few fish!**
