Step 1 of 2
Prepare the area to be polished making it smooth and in the final desired shape. If necessary, use Diamond Pro (FGM) sandpaper disks in grits G, M and/or F, or Diamond ACI and ACII (FGM) pastes in medium and fine grits, for finishing prior to polishing. This step is important as the brightness will strongly depend on the initial conditions of the surface.
