Part One: Cut It!
1. Let's talk about the sandpaper. If you are cutting a factory paintjob, grab some 3000. The factory clear is very thin, and anything coarser than 3000 will take off way too much clear and increase the chance of sanding through to the basecoat. For a custom paintjob, pick up some 1200 and some 2000. The 1200 will make short work of the orange peel, and the 2000 will help speed up the polishing portion of the job by removing the larger scratches left by the 1200. Before you start sanding anything, let the paper soak in clean water for a minimum of 15 minutes (overnight is preferred).
