Hello, I have 20 Lug Nuts to powdercoat – I made a metal frame to hold all 20 so I can shoot and heat treat all 20 at once. My question is about grounding the Nuts – doing each one doesn’t seem practical so I am hoping I can clamp the ground wire to the wire frame – although the nuts will be just sitting on a vertical metal pin about 1/16? dia I hope they will ground enough for good coating. The frame was made from a oven tray – I cut many of the horizontal frame arms and turned them vertical until I had 20 vertical metal studs. I believe the metal frame is steel with chrome coating. Do you think it will carry the ground through out the frame back to the ground clip with the nuts just sitting on the frame?
