When it comes to fly tying, durability and precision are key. Whether you’re crafting delicate nymphs or sturdy streamers, the right head cement can make all the difference in ensuring your flies last through countless casts and strikes. **Hareline’s HARD AS HULL HEAD CEMENT** is a top-tier choice among fly tyers, offering three specialized variants: **Original, Penetrator, and Thinner**. But how do you choose the right one for your needs? In this guide, we’ll break down each option to help you make an informed decision.
## **1. HARD AS HULL HEAD CEMENT – Original**
The **Original** formula is the go-to for general fly tying applications. It provides a strong, glossy finish that protects thread wraps and secures materials in place.
### **Key Features:**
– **High durability** – Resists abrasion from fish teeth and rocks.
– **Fast drying** – Cures quickly without leaving a sticky residue.
– **Versatile** – Works well on most fly patterns, from dry flies to saltwater streamers.
### **Best For:**
– Securing thread wraps on hook eyes.
– Adding a protective coating to the heads of nymphs and wet flies.
– General reinforcement on a variety of fly patterns.
## **2. HARD AS HULL HEAD CEMENT – Penetrator**
The **Penetrator** variant is designed to seep deep into materials, locking them in place from the inside out. This makes it ideal for flies with dense wraps or synthetic fibers.
### **Key Features:**
– **Deep penetration** – Flows into thread and material layers for superior hold.
– **Flexible yet strong** – Maintains durability without becoming brittle.
– **Great for synthetics** – Works exceptionally well with UV resins and synthetic dubbing.
### **Best For:**
– Flies with heavy thread wraps (e.g., articulated streamers).
– Synthetic materials like EP Fibers or Laser Dub.
– Flies that require internal reinforcement.
## **3. HARD AS HULL HEAD CEMENT – Thinner**
If you need a lighter, more fluid consistency for delicate flies, the **Thinner** version is the perfect choice. It provides a smooth, even finish without weighing down small patterns.
### **Key Features:**
– **Low viscosity** – Spreads easily for a fine, controlled application.
– **Minimal buildup** – Ideal for small flies where excess cement could affect buoyancy.
– **Quick absorption** – Works well on delicate materials like CDC or fine thread.
### **Best For:**
– Small dry flies and emergers.
– Flies requiring a subtle, lightweight finish.
– Applications where precision is critical.
## **How to Apply HARD AS HULL HEAD CEMENT**
1. **Prepare the fly** – Ensure thread wraps are tight and materials are properly positioned.
2. **Apply sparingly** – Use a fine applicator brush or a bodkin for controlled placement.
3. **Let it cure** – Allow sufficient drying time before fishing (drying time varies by formula).
## **Final Thoughts**
Choosing the right **HARD AS HULL HEAD CEMENT** depends on your fly pattern and tying style. The **Original** is a reliable all-rounder, the **Penetrator** excels in deep reinforcement, and the **Thinner** is perfect for delicate applications.
