How smooth should counter be before using aqua-poxy?

Hey, we just poured our counters 2 days ago and i got them as smooth as possible with the steel trowel. I am curious to how smooth they should be after dry sanding. I used 220 grit on the orbital sander to start with and it seemed like it was leaving scratches. I can change to a higher grit but what smoothness can I look forward to achieving with this? Or are they going to be rough regardless? With that, will the aqua-poxy fill the roughness and give it a smooth finish? Thanks in advance. Chris

From what I've read (I have not done my first countertop yet) you should wet sand up to 220 grit. If you go higher than 220 grit, wet glasses/plates will leave a ring even after it's dry. Go to 220 then seal it.
