Absolutely, I agree with both of you; grit does not just apply to sandpaper. Also, fun fact, P800 is not the same as 800 in grit scale. Just a number (i.e. 800) usually refers to ANSI, which is a different scale. - Claire Porter 2022.09.19

Grit can also refer to the coarseness or fineness of other polishing media. For example, we also use diamond polishing media that has an associated grit. - Vanessa Meschke 2022.09.19

Fine grit is denoted by higher numbers, and coarser by lower numbers - Rachel Orenstein 2022.09.19
