The McMagic Micro Burnishing Papers by McDermott are washable & reusable shaft conditioning system for smoothing shaft. For very rough shafts begin with the Green sheet. For shafts that have been recently polished begin with the Yellow or Blue sheet. It might not be necessary to use the entire series each time. **Instructions: Cradle the sheet of sand paper around the shaft and stroke using a circular twisting motion. Avoid creating excess heat through friction. Proceed by using the finer grit sheets until the effect of the previous sheet is eliminated.**
