Use and fit

Choose the single compound when you have enough cutting grit and need to replace only the final grade. Use it after the stones are already smooth, in a barrel cleaned of earlier abrasives. It is the same family of final compound MJR includes in some full assortments.

Questions before buying

When is a single polishing compound enough?
