Permalyn gun stock finish remains a popular choice among gunsmiths and DIY enthusiasts alike for its durability and relatively easy application. But is it the best choice for your firearm? This in-depth guide will explore Permalyn's properties, application techniques, potential drawbacks, and viable alternatives. We'll cover everything you need to know before reaching for the Permalyn.
Understanding Permalyn Gun Stock Finish
Permalyn is a type of polyurethane finish, specifically formulated for use on wood gun stocks. It's known for its tough, protective coating that resists scratches, dents, and the general wear and tear a firearm endures. This makes it a go-to for both hunting rifles seeing regular field use and prized collector pieces requiring preservation. The finish's chemical composition creates a hard, durable surface that protects the underlying wood from moisture, UV damage, and impacts. This durability is key, especially given the often harsh conditions firearms face.
Key Features and Benefits of Permalyn
- Durability: Permalyn is renowned for its resilience against scratches and abrasions, ensuring your gunstock remains protected from the elements and everyday handling.
- Water Resistance: Its excellent water resistance protects the wood from moisture damage, preventing warping, cracking, and rot. This is crucial for firearms exposed to rain, snow, or humidity.
- UV Protection: Permalyn offers UV protection, preventing fading and discoloration of the wood's natural color over time. This is particularly beneficial for firearms stored in direct sunlight.
- Easy Application: While requiring patience and careful technique, Permalyn is considered relatively easy to apply compared to some other gunstock finishes, making it suitable for both experienced gunsmiths and hobbyists.
- Widely Available: Permalyn is readily available from various gunsmithing supply retailers, both online and in physical stores.
Applying Permalyn: A Step-by-Step Guide
Proper application is crucial for achieving a beautiful and durable finish. Here's a breakdown of the process:
-
Preparation is Key: Begin by meticulously sanding the wood stock to a smooth, even surface. Use progressively finer grits of sandpaper, working your way up to at least 320 grit. This ensures optimal adhesion of the finish.
-
Cleaning: Thoroughly clean the stock to remove any dust or debris from the sanding process. A tack cloth is ideal for this.
-
Thinning (Optional): Depending on the specific Permalyn product and desired consistency, you may need to thin the finish with a suitable solvent, usually mineral spirits. Always follow the manufacturer's instructions precisely.
-
Application: Apply thin, even coats using a high-quality brush or spray gun. Avoid heavy coats, as these are more prone to running and imperfections. Allow ample drying time between coats.
-
Sanding Between Coats (Optional): Light sanding between coats (using at least 400 grit sandpaper) helps to level the surface and create a smoother final finish. Thoroughly clean the stock after sanding.
-
Final Coat: Once all coats have been applied and dried, you may choose to lightly buff the stock to achieve a high-gloss sheen.
Troubleshooting Common Permalyn Application Issues
| Problem | Solution |
|---|---|
| Runs or Sags | Apply thinner coats, allow more drying time between coats |
| Brush Strokes | Use a higher-quality brush, apply smoother coats |
| Uneven Finish | Sand between coats more thoroughly, ensure even application |
| Dust Nibs | Use a tack cloth to remove dust before each coat |
Permalyn Alternatives: Exploring Other Gun Stock Finishes
While Permalyn offers excellent protection, other options exist, each with its own strengths and weaknesses:
-
Tru-Oil: A penetrating oil finish that provides a more natural look and feel, though it offers less protection than Permalyn. It's typically applied in multiple thin coats.
-
Birchwood Casey Super Seal: A durable, water-based polyurethane finish that’s easier to clean up than Permalyn. It offers similar protection but may not be as hard-wearing.
-
Tung Oil: A classic wood finish offering a natural, rich look. However, it requires more maintenance and offers less protection against scratches and water damage than Permalyn or polyurethane.
Conclusion: Choosing the Right Finish for Your Gun Stock
Permalyn gun stock finish provides a durable, protective coating with relatively easy application. However, the best choice depends on your specific needs and preferences. Consider factors like the firearm's intended use, the desired aesthetic, and your experience level when selecting a finish. Always follow the manufacturer's instructions carefully for optimal results. Whether you choose Permalyn or an alternative, proper preparation and application are key to achieving a beautiful and long-lasting finish for your prized firearm.
