Permalyn gun stock finish has long been a favorite among gunsmiths and DIY enthusiasts for its durability, water resistance, and attractive, natural look. This comprehensive guide delves into everything you need to know about Permalyn, from its properties and application to troubleshooting common issues and exploring alternatives.
What is Permalyn Gun Stock Finish?
Permalyn is a type of oil-based finish specifically formulated for use on gun stocks and other wooden firearm components. It's known for its ability to penetrate deeply into the wood, hardening and protecting it from the elements while preserving the wood's natural grain and color. Unlike some finishes that create a hard, plastic-like surface, Permalyn provides a more durable, yet naturally finished look and feel. This makes it ideal for preserving the beauty and functionality of a firearm's stock.
Key Properties of Permalyn Gun Stock Finish
- Deep Penetration: Permalyn soaks into the wood fibers, rather than sitting on top, offering superior protection against moisture and scratches.
- Durability: It creates a tough, resilient finish capable of withstanding the rigors of regular use and handling.
- Water Resistance: Provides excellent protection against water damage, keeping the wood from warping, cracking, or swelling.
- Natural Look: Permalyn enhances the wood's natural beauty without obscuring its grain or creating a glossy, artificial appearance. It allows the wood's character to shine through.
- Easy Application: While requiring multiple coats, the application process itself is relatively straightforward.
- Non-Toxic (relatively): While it's crucial to use in a well-ventilated area and wear appropriate safety gear, Permalyn is less toxic than many other chemical-based finishes.
Applying Permalyn: A Step-by-Step Guide
Achieving a professional-looking finish with Permalyn requires patience and attention to detail. Here's a breakdown of the process:
1. Preparation is Key
- Sanding: Start by sanding the stock to a smooth finish, typically using progressively finer grits (e.g., 120, 180, 220, 320 grit sandpaper). This step is crucial for optimal penetration and a flawless final result.
- Cleaning: Remove all sanding dust with a tack cloth or compressed air. Any remaining dust particles can lead to imperfections in the finish.
2. Applying the Finish
- Thin Coats: Apply several thin coats of Permalyn, allowing ample drying time between each coat (typically 24 hours or more, depending on temperature and humidity). Avoid thick coats, as these can lead to runs and uneven drying.
- Rubbing Down: Lightly sand with very fine sandpaper (e.g., 400 grit) between coats to smooth out any imperfections and ensure a uniform finish. Again, remove all dust before applying the next coat.
- Final Polishing: After the final coat has thoroughly dried, you can optionally polish the stock to achieve a higher luster. This can be done using a suitable polishing compound.
3. Drying and Curing
Allow the Permalyn to cure completely before handling or using the firearm. This process can take several days or even weeks, depending on the number of coats and environmental conditions.
Troubleshooting Common Permalyn Issues
- Runs or Sags: This indicates that the coats were too thick. Sand down the imperfections and reapply thinner coats.
- Uneven Finish: This might result from inadequate sanding or insufficient drying time between coats.
- Dust Nibs: These are small particles of dust trapped in the finish. They can often be removed with careful sanding and re-application of a thin coat.
Alternatives to Permalyn
While Permalyn is a popular choice, several other gun stock finishes exist, each with its own advantages and disadvantages. Some popular alternatives include Tru-Oil, linseed oil, and polyurethane. Research each carefully to determine which best suits your needs and preferences.
Conclusion
Permalyn gun stock finish offers a classic, durable, and attractive option for protecting and enhancing the beauty of your firearm's stock. By following the proper application techniques and addressing potential problems, you can achieve a professional-looking finish that will stand the test of time. Remember, patience and attention to detail are key to success.
