I'd stay away from halfrauds jobbies.
Steve, it will take all day to do the car properly. You need to prep the car - wash, clay, rinse, dry, which can take an hour or two. To polish properly took me in the region of four hours - go slowly, work the polish, make sure the pad doesn't dry out or overheat, etc. Not to mention the taping up. Once you've polished, IPA wipedown and apply glaze, then wax or sealant. To do my car properly took me 12 hrs the first time I did a full detail. That includes brakes/wheels/rubber trim/windows.
You can always break things up and do things like wheels/exhaust/trim/etc on a separate day but given your car is outside, I'd hit the paintwork all in one go. You could always do a light pass with a finishing pad and something very mildly abrasive light lime prime - would be enough, plus it already contains a glaze/cleanser, so you could skip to waxing.
