Thank you everyone that responded on the tooling die marks post issue. We tried everything you suggested: heat, chemical etching, coating, buffing, sandblastic and plastic overlays. In the end, a combination of resetting our CNC machining tool paths, finer grit sandpaper and a mechanical buffing machine did the trick. Since it was a combination of answers, I’ve sent out some people care packages for their help and definitely owe Diane some goodies for her contributions as well.
