wet sanding help

No.

You will tear the metallics out on the top of the orange peel texture. If you want it smoother, scotch brite the paint job, clearcoat over it and color sand/ wet sand and polish the clear. Scotch brite is soft enough that it will not affect the metallic layout done evenly, because it goes down into the natural orange peel texture of the spray/ pattern on the panel.

If you don't want to live with it the way it is, this is the easiest solution.
