3/5 After sanding to 1500 grit, there sre still some very minor sanding lines visible. Sanding paste is a mix of beeswax, oil, and diatomacious earth. The grit of the paste is actually more coarse than the last sandpaper, but it breaks down and getrs finer as it is worked in. A generous amount goes inside, then the bowl is spun and the grit worked in until it is smooth. Then it is removed with more denatured alcohol and the whole process repeated on the outside.
