Once you've blocked with 320 you're done with shaping and all that the 600 wet is doing is smoothing out the 320 scratch. I do it using a #20 3M soft pad (they call it a sponge pad which might lead you to believe that it absorbs water but it doesn't). Watch the 600 wet on edges and sharp radius because it will cut through suprisingly fast!
