If you're not used to polishing with a machine, then yes a R/O (Porter Cable 7424) is the way to go starting out. You'll not damage paint with this device unless you drop it on the paint.
Rotary is much better for paint correction, however, you have to be better skilled on using these. Porsche paint is very soft and too many people can get into trouble fast with a rotary. Yes, it can damage/burn paint if not used correctly or in un-trained hands.
I too have black, and Porsche paint being soft, the random orbital will work fine with the correct pads and polish. For mild marring, always start mild pads/polish and then work up if the results do not correct the issue.
Deeper will require a harder foam pad and a more agressive polish. But, again, it's soft so most times an orange pad (cut/polish combo foam) and a bit more agressive Menzerna polish such as SIP or just IP will correct it, then you need to use a polish pad and a softer polish such as Menzerna 106FF or 105FA, or FP. Then, if you want to use a sealant, you'll need to wash off the oils used in the polish as a lube. If using a wax, just wax away.
Sure detailers can and still use a glaze, which hides/fills micro-marring and poor paint correction from polishing with an unskilled person or too agressive pads and no time to finish up. There are many glazes from major mfg (3M, Meguiars, Zymol, Menzerna) to private labels (ClearKote Moose, Poorboys, Sonus, etc). SOme work well, others not so well.
You can always tell by stripping wax off the "detailed" finish and see if you find the marring once again or buffer trails. See it all the time from other "quick detail" wash shops.
Always, plan ahead, give yourself enough time to to a full polish. If you do not have the time/skill etc, then seek out other owners and find out who they use to detail their cars and just pay to have the pro do it, then enjoy driving the remaining time!
