I used a buffing drill bit. Guy I got the cerium oxide from also said he was unsuccessful. There is a company called "glassscratchout" they have a Durban branch and quoted me R1200 to remove all scratches completely and call out. They sand down to the depth of the scratch and then use their buffing technique to get the glass back to normal. If you don't mind spending the money id go for this option.Did you try manually or with a polishing machine?
