An AIO may not be enough if the paint has swirls and such. You're better off using a polish or glaze compound to first remove the defects. More work but good results. Pads are normally labeled for their intended use, so if you decide to just do the AIO I'd use a polishing/finishing pad such as this:
Green Polishing/Finishing Foam 6.5" - Use this foam to apply one-step cleaner waxes. It is a balance of polishing and finishing that is perfect for all-in-one product application.
