Painting a polymer folding stock might seem daunting, but with the right preparation and technique, you can achieve a professional-looking finish that enhances both the aesthetics and functionality of your firearm. This guide will walk you through each step, ensuring a durable and attractive result. This process applies to most polymer folding stocks, whether for AR-15s, AKs, or other platforms. Remember always to follow all relevant firearms safety regulations and laws.
Preparing Your Polymer Folding Stock for Painting
Before you even think about grabbing a paintbrush, thorough preparation is key. This will ensure the paint adheres properly and lasts. A poorly prepped stock will lead to peeling and chipping, negating all your hard work.
Cleaning is Crucial
Begin by thoroughly cleaning your polymer folding stock. Use a degreaser like brake cleaner or isopropyl alcohol to remove any oils, dirt, or grime that may be present. This is especially important if the stock has been handled frequently. Use a clean cloth or brush to scrub every inch of the surface, paying close attention to crevices and joints. Allow it to dry completely before proceeding.
Surface Roughening: Enhancing Adhesion
Polymer is a smooth surface, and paint doesn't adhere well to smooth surfaces. You need to roughen it up to create a better bonding surface. There are several ways to achieve this:
-
Scotch-Brite Pad: This is a popular and effective method. Use a medium-grit Scotch-Brite pad to lightly scuff the entire surface of the stock. Avoid applying too much pressure, as you don't want to damage the polymer. The goal is to create a slightly textured surface, not to sand it down.
-
Fine-Grit Sandpaper: If you prefer a more controlled approach, use fine-grit sandpaper (around 320-400 grit). Again, lightly sand the entire surface, using even strokes. Avoid applying too much pressure.
-
Chemical Etch (Optional): For a more aggressive approach, you can use a plastic etching primer. This creates microscopic pores in the polymer, providing even better paint adhesion. This step is particularly helpful with very smooth plastics.
After roughening, wipe the stock down again with a clean cloth to remove any dust or debris created during the process.
Masking (if needed)
If you only want to paint certain areas of your folding stock, carefully mask off the sections you want to keep their original color. Use painter's tape and newspaper or masking film to create clean lines and prevent accidental paint application.
Choosing the Right Paint
The type of paint you choose significantly impacts the final result. Here's a breakdown of suitable options:
-
Cerakote: This is a high-end ceramic coating known for its exceptional durability and heat resistance. It's a popular choice for firearms, but it requires specialized equipment and application techniques.
-
Krylon Fusion for Plastic: This is a readily available spray paint specifically designed for use on plastic and other challenging surfaces. It provides good adhesion and a durable finish.
-
Rust-Oleum Painter's Touch 2X Ultra Cover: Another readily available option, this paint offers good coverage and durability, although it might require multiple coats.
No matter what you choose, it's vital to select a paint that is designed for outdoor use and is resistant to scratches and abrasion.
Painting Your Polymer Folding Stock
Once you have chosen your paint, follow these steps for a professional-looking finish:
-
Thin Coats: Apply several thin coats of paint instead of one or two thick coats. This minimizes runs and ensures even coverage. Allow each coat to dry completely before applying the next.
-
Even Application: Maintain a consistent distance from the stock while spraying to prevent uneven application. Use smooth, sweeping motions.
-
Multiple Coats: Depending on the paint and desired opacity, you'll likely need 2-4 coats. Allow each coat to dry thoroughly according to the manufacturer's instructions.
-
Drying Time: Allow ample drying time between coats and after the final coat. This ensures the paint cures properly and achieves maximum durability.
Finishing Touches and Clear Coat
Once the paint is completely dry, you can add a clear coat to protect the finish and enhance its durability. A high-quality clear coat, such as a satin or semi-gloss polyurethane, will help to resist scratches, chips, and UV degradation. Apply multiple thin coats, allowing each to dry thoroughly.
Post-Painting Considerations
-
Testing: After the paint and clear coat have fully cured, thoroughly test the folding mechanism to ensure it operates smoothly and without interference.
-
Maintenance: Regularly clean your painted stock to maintain its appearance and prevent dirt and grime from building up.
-
Storage: Store your firearm in a safe, dry place to protect it from the elements and prevent premature degradation of the paint.
By following these steps, you can successfully paint your polymer folding stock and enjoy a customized and durable finish. Remember to prioritize safety and always refer to the manufacturer's instructions for your specific paint and firearm.
