Honestly, on a factory clear coat I wouldn't recommend wet sanding to remove your orange peel - there just isn't that much clear on a factory paint job, just 2 mils or so (that's 2/1000 of an inch!). With 800 grit paper you'd go through it in no time if you don't know what you're doing. Even with 2000 grit you can remove more paint than you realize, and the only way you're going to effectively remove those sanding marks is with a rotary buffer, wool pad and a heavy cutting compound. I just don' t think it's worth risking on a factory paint job.

Removing half of that clear is enough to severly compromise the UV protection afforded by the clear coat, and you're setting yourself for serious paint issues down the road. I work for Meguiar's and we've been working directly with all the major paint manufacturers for years, and we've been in the OEMs for decades. We've got as good if not better a handle on this than most, for what it's worth.
