Can I sand and polish the epoxy?

After the epoxy is cured for at least a year, it is possible a VERY SKILLED person with polishing skills could use a 3M product called “Finesse-it 2”, which is a high gloss polishing compound, and could remove the scratches and leave a high-gloss. However, if they don’t know what they are doing, they could use too high a speed to polish and would cause the epoxy to smear.
