I am planning to lap my new Naniwa 12k and figured I would start lightly with some 600 grit sandpaper on a flat piece of marble I have and then move up to 1000/1200 grit. That was until I asked myself about the prefix "P" before the "600.
So now I know that P means the FEPA standard. So if I want to use silicon carbide sandpaper to mimic Atoma 600 and 1200 diamond lapping plates, do I want P600 and P1200?
