I wonder if the grit is the same in your country as in mine.
i think it is some "peaks per area" reading so i guess it is different
between
metric and imperial.
Does anyone know that?
I use 600 grit for the pcb prep.
this is very fine paper, the coarsest you get is 40,
60, 80 or 100 being used for common wood sanding.
But some pads could be bigger you know....
