Subj: RE: POWDER COATING SET UP FOR MG
Next question: beings we're dealing with dc voltages and "grounding charges"
would I be correct in thinking that the palstic and/or paint contains some
sort of conductive substance? Or is there a static charge that causes the
plastic to cling to the metal part being painted? I would assume that the
metal pieces being painted are, themselves, grounded - to complete the
circuit. ????
