David, Thank you so much. I wonder if part of my problem is that the lap I used for a pre-polish wasn’t a fine enough grit. I will definitely purchase some BATTs. Do you charge with diamond powder, spray, or the diastiks? Where do you purchase the Chinese toppers from? I am hoping once I try the lava soap on my old laps they might have some life left in them, but it is good to know if they are past the point of no return (and for the coarser grits) there is a reasonably priced option for replacement.
