Personally I would start that with 800 or 1000 and lots of water working up to 2000 then compound it. You will feel the rough surface coming off as you get the hang of it, don't press on too hard. I don't understand the 240 = 600 wet analogy and the pieces of grit per inch theory. Wet paper cuts finer because it is lubricated in my experience and the grit is not measured in pieces per inch it is the size of the particles stuck to it. I had some 40 grit sheets and you wouldn't go near a car with it unless it was red rusty. I do use 80 for quick filler removal and shaping and being a tight git I treat worn paper as a finer grade occasionally. Al Ox dry cuts more freely and resists clogging and silicon carbide is the one for wet and dry on paintwork.
