Over the weekend I did my first wet (my first EVER wet). I have a diamond generated 8" f/6.8 plate glass that I am working. I started with 80 grit and worked the glass for about 90 minutes.


Under my magnifying glass I see pits of varying sizes. Having never done this before, I have no idea if I am ready for the next size grit.


As I look at the surface, it seems to be evenly pitted. There are a multitude of sizes, but the largest ones seem to be evenly distributed across the surface and there is an upper limit to the size of the pits.


My guess is that I am ready for the next grit size.


Another question...in grit labeled 80, does that mean the largest size particle is 80 and there may be fines mixed in? In otherwords, is the number the largest size particle in the container?


This would then make sense as to why I have a multitude of pit sizes across the surface.


Thanks for any insights,
Dave
