The sanding starts from 240 grit. Coarse sandpaper, like 120 and lower, would only cause chipping. These small sanding bands come only in a very few grits, so I actually don’t have too much choice. The 240 one is followed by 400 grit.
Cleaning the bands is necessary. This little brush does the job perfectly.
The bands have to be replaced from time to time.
When the sanding is completed it is time to use felt wands and polishing compound.
Last stage is always wet. Cerium oxide has never failed.
After few hours it’s ready. If it’s not a drinking glass I use paper towels and diluted vinegar to clean the glass.
Now it’s time to give it to my wife so she could find a use for it.
