So much fun
Really depends where the stone is at or what it needs.
There are nylo- grit brushes that are easy to use on drivers 17 inch and more
Then there are trapezoid brushes in silicone Carbide grits from like 24 and up
Same with diamond brushes.
If you are just refinishing the surface the nylo-grits from malish should work fine.
They start at 46 grit and run up to 500 grit.
I suggest you get a set starting at 80 up to 500. (80-120-180-500)
Then supplement with dip's to give you a nice finish .
