Too much work!
I presume you are working with base coat-clearcoat. Start block sanding with 600 grit (WET with a drop of dishsoap in the water) then double that (1200) do most the work with the 600. The 1200 takes out the tracks of the 600. Then use medium grit compound (with a wool pad on an electric buffer) then polish or glaze. The only thing u get goin to finer wet sanding is exercise! And as soon as u buff with the medium compound ur wife will disregard what she said about u earlier. It really does work...enjoy standin back, havin a beer and grinnin!
