I decided to just go for it. Worked out better than I had hoped.I have only had my polishing wheel for a couple of days, so was just practicing. After some old cellidor scales and some brass liners, I figured just try the magnifying glass.I chose the lowest rpm my drill would go, the finest polishing wheel and compound I have, and used light pressure.Most of the scratches are gone now. It’s not perfect, but it’s not worth the risk to take it further. As gregozedobe mentioned, that would require coarser polishing compound.Thanks so far guys!
