Frequently Asked Questions

What is GunKote and how does it differ from Cerakote?

GunKote is a heat-cured epoxy finish known for its durability, heat dissipation, and abrasion resistance. It's considered more forgiving to apply than Cerakote, making it a good choice for DIYers, while offering comparable real-world durability.

What is the recommended preparation process for applying GunKote?

Proper preparation involves blasting firearm components with 120-grit aluminum oxide to create adhesion. For anodized parts, a light blast to remove sheen is sufficient. Thorough degreasing with acetone is crucial to ensure a clean, residue-free surface before painting.

What are the correct curing instructions for GunKote?

After application, GunKote must be baked at 325°F (163°C) for 1 hour to properly cure. Allow the parts to cool completely before reassembly.

Can GunKote be applied to plastic firearm components?

Yes, GunKote can be applied to plastic stocks. For materials like Magpul or B5, they can be baked at the standard 325°F. For more heat-sensitive plastics, KG offers KG-180 for lower temperature curing.

What are the key techniques for airbrushing GunKote effectively?

Start by painting hard-to-reach areas first. Maintain consistent movement and control paint flow with the airbrush trigger. For internal areas, use a light dusting technique with air to help dry the surface and prevent overspray.
