When I have to recondition the surface of my American Mutt I have had good success using 30 grit SiC powder.
I have used 60 and 90 in the past but they start to break down too quick.
Like Benjamin said using a good amount of pressure keeps exposing new grit on the AM , I have also found keeping it well saturated helps things out too.
I was hoping I didn’t have to resort to loose sic powder. But maybe that’s the only thing that does the job right. For now I still have the manticore for coarse jobs which is fantastic btw.
