What are you wetsanding clearcoat with?

[sunoco67]

What procedures are you guys using to finish sand the clearcoats. I have heard some guys are using a applying 2 coats of hi solids clear to the topcoat, wet sanding with 1000 grit paper reclearing 2 more coats and then wet sanding 1500,2000,3000 for a super flat no orange peel finish.

Thanks in advance
