9 grits of micro mesh from 1500 to 12000. Like these: https://www.amazon.com/Micro-Mesh-Sanding-Pads-Grits/dp/B0756MT6X8/ or these: https://www.amazon.com/Sanding-Stopper-Polishing-Perfect-Materials/dp/B000H6EC4C/

I highly recommend using these. It takes more time than steel wool but works better and cleaner.
