Dale, we use 3m polishing compound. But to remove scratches and resurface we use wet and dry sand paper starting with 400 grit then 600, 800, 1000, 1500, 2000 and then 2500. Final coat use the 3m polish. If your counter tops do not have any deep scratches you can start with 600 grit sand paper. Use a sanding block and practice on an inconspicuous area first.
