I’m refining my workflow for metallographic sample prep and want to improve the consistency and surface quality during the final grinding and polishing stages. The choice of polishing pads for sample preparation seems to make a big difference in how well scratches from earlier grits are removed and how uniform the final surface turns out.
I found this reference that outlines different pad options and their intended use cases:

For those who have tried various pad materials and configurations, what combinations have given you the best balance of flatness and minimal surface damage before etching or microscopy?
