Electroless Nickel Teflon has continually proven to outperform traditional Anodizing and Phosphate coatings by leaps and bounds! The increased reliability, corrosion resistance and ease of maintenance make this upgrade a no-brainer.

Nickel Teflon does not hide them as well. In no way shape or form will these blemishes affect functionality. Features: Forged & machined by Cerro Forge (Key Hole)
