If it were me Brian, I'd go with the Poorboys SSR2 on either a Meguiars yellow polishing pad (or a Lake Country 'Green') and see how that fairs with the swirl removal. If you have SSR1 as well, it wouldn't hurt to give it a pass over with that on either a Meguiars finishing pad (the tan one), or a Lake Country Blue just to refine the finish.

If you don't have those Poorboys ones and are buying new, then either go for a combination of Menzerna PO85RD 3.02 'Intensive Polish' followed by PO85RD Final Finish if the swirls are quite extensive, using the same pads as above. (these 2 Menzerna polishes are roughly direct substitutes for the SSR2 and SSR1).

Alternatively if the swirls aren't too bad you could get away with a single product like Menzerna PO106 Final Finish which might be enough to tackle them on its own and will finish down to a great gloss level.

Just be careful if it's your first time with a rotary, start with the least abrasive polish & pad combo you have and work upwards if you don't get the correction you want. Also keep checking the area you're doing and feel for the temperature of the panel and don't use it on painted plastic parts like the bumpers etc. as they can't dissipate the heat build up that rotaries create like metal panels can - random orbit/dual action machine polishers are usually used on these bits.
