Can You Cerakote Polymer Guns? A Comprehensive Guide
Cerakote is a popular choice for firearm customization, offering durability and aesthetic appeal. But when it comes to polymer-framed guns, the question arises: Can you Cerakote polymer guns? The short answer is yes, but it's not as straightforward as coating metal firearms. This guide will delve into the nuances of Cerakoting polymer, exploring the process, preparation, and considerations for achieving a successful and lasting finish.
Understanding the Challenges of Cerakoting Polymer
Unlike metal, polymer is a less porous material. This means that the Cerakote coating needs extra preparation to properly adhere. If not properly prepared, the coating may peel, chip, or otherwise fail prematurely. The success of Cerakoting a polymer firearm hinges on meticulous surface preparation. This is where many DIY attempts fail.
Preparing Your Polymer Frame for Cerakote
This stage is critical. Skipping steps or rushing through the process will almost certainly lead to a subpar finish.
1. Thorough Cleaning: Begin by thoroughly cleaning the polymer frame with a degreaser. Remove all oils, dirt, and grime. This ensures proper adhesion. Isopropyl alcohol (IPA) is a common and effective choice.
2. Surface Roughening: This is arguably the most important step. Polymer is inherently smooth, and Cerakote needs texture to grab onto. Several methods can achieve this:
-
Scotchbrite Pad: Using a fine-grit Scotchbrite pad, gently scuff the entire surface of the polymer frame. Avoid excessive pressure, as this can damage the polymer. Aim for a slightly textured finish, not deep scratches.
-
Sandpaper: Fine-grit sandpaper (around 400-600 grit) can be used, but requires extra care to avoid sanding too aggressively. This method offers more control but is more prone to errors if not done correctly.
-
Chemical Etching: Some specialized primers are designed to etch the polymer surface, improving adhesion. These are often recommended for particularly smooth polymers. Always follow the manufacturer's instructions precisely.
3. Cleaning Again: After roughening, thoroughly clean the frame again with IPA to remove any dust or debris created during the surface preparation. This is crucial for a clean, flawless finish.
Applying the Cerakote
Once the polymer frame is properly prepared, applying the Cerakote is relatively straightforward, though proper technique is still essential.
-
Primer (Often Necessary): A dedicated polymer primer is highly recommended. This provides an additional layer of adhesion between the polymer and the Cerakote topcoat. Follow the manufacturer's instructions for application and drying times.
-
Cerakote Application: Apply the Cerakote topcoat in thin, even coats. Allow ample drying time between coats, following the manufacturer's recommendations. Multiple thin coats are better than one thick coat to prevent runs and ensure a smooth finish.
-
Curing: Finally, cure the Cerakote according to the manufacturer's instructions. This usually involves baking the firearm in an oven at a specific temperature for a set duration. Improper curing can lead to coating failure.
Choosing the Right Cerakote for Polymer
While many Cerakote colors and finishes work well on polymer, it's vital to choose a formulation suitable for plastics. Always check the manufacturer's specifications to ensure compatibility.
Important Considerations
-
Professional Application: For best results, especially on valuable firearms, consider professional Cerakoting. Experienced professionals possess the knowledge and equipment to achieve a superior finish.
-
Disassembly: Before beginning, completely disassemble the firearm. Only the frame should be coated. Reassembling incorrectly can damage the firearm.
-
Safety: Always follow safety precautions when working with solvents, primers, and Cerakote. Work in a well-ventilated area.
By following these steps carefully and using the right materials, you can successfully Cerakote your polymer gun. Remember, proper preparation is key to achieving a durable and attractive finish. However, if you're unsure about any aspect of the process, it’s always best to seek professional help.
