Thanks for the comment Mike. I have a Facetron. I’ve completely avoided the 3000 grit topper (it is quite useless). I’m using a 600 & 1200 topper, with a pre-polish with a D-Lite 3000 mesh. Polishing has been good with Lighning Lap Cerium and Aluminum oxide toppers.
I haven’t been brave enough to buy/use a metal lap with diamond powder yet.
