for me, 220 grit leaves a lot of lines underneath a virgin layer of brightside. what i'm doing now is using 220g to get rid of orange peel and driplines, then i'll follow with at least a 600g (what i already have).

i'm trying to wetsand 2nd to final layer smooth, so when i finally add that last layer, it will lay so smooth, that i won't have to wetsand it. i'll just let it dry for a month and buff it.
