I would only polish if swirls are present or if a more desired reflective apearance is wanted. Polishing always takes some paint material when done. Already using clay and compound will allow the wax to bond better to the paint.
Stress would come from a wire for instance being too short and causing a constant pulling against the crimp area of the eyelet. The ground wire looks to be 12 gauge. As far as the ring of the eyelet being so tight from being torqued down one might see metal being pushed out in the area. Ford...

@slat You are correct that was a common issue. You had to shift with perfect timing to keep any backlash noise from happening. I never knew anyone that could shift in perfect timing every time. The noise was there 1 through 3. Shifting at 3k or above made things better. I'm not saying it is...
