Prepping and Painting Fasteners



FYI, Most OEM Automotive "Black" Fasteners are MANGANESE Phosphate NOT Zinc Phosphate and NOT Black Oxide !!!!

I have recently had a ALOT of them done at a commercial plating vendor who rotates them in a Barrel in the tank.

Ive also done my own Mang Phos and Zinc Phos using chemicals bought from PALMETTO !!!
