To take a slightly different approach - consider polishing a test panel, see how it looks; compound and re-polish if necessary. You might like what you see enough to avoid or postpone the wet sanding for now. Orange peel isn't pretty to look at, but it hides a ton of minor day to day flaws. A good polish, working on your technique, maybe adding a small polisher for nooks and crannies to go with your large one - these might be a good first approach to the car. The Adam's 3" Swirl Killer (12mm Mini) has been a great addition for me in this regard.
Jimmy's Shelby looks spectacular, and also reflect a good deal of experience. If nothing else, I'd recommend getting some scrap body panels from a salvage yard to practice on.
