Try a bit of Meguiar's ScratchX. Its probably the only product I buy at the local auto stores like PepBoys, all the other stuff I buy has to be purhased from Pro Detailer sites like Autogeek.net and Autopia. Try the ScratchX with a Porter Cable 7424 orbital polisher which you can buy on Sale at Coastal Tool. It will speed up the process because polishing out micro marring by hand can take an eternity.
P21S paint cleaner or 1Z paint polish is also good before using the ScratchX.
Best to work with a 100% pollutant free surface.
Then as others have suggested, I would use the Klasse Twins (All in One and Sealant Glaze). S100 is a great carnauba topper wax for $15 once you have added all your Klasse SG layers. I top with S100 once a month.

A word of advice. Buy some Waffle weave towels from Autopia. I keep them in my car during winter so that the car wash(hand car wash only) guys have a scratch free/swirl free towel to dry the car with. When winter is over I never go to a car wash. This where 90% of the swirling happens due to using dirty wash mits and cheap cotton drying towels. Avoid all auto store towels, even the microfiber ones they are bad quality and all are made in China with cheap threading machines. Look for the Korean made ones they use much more expensive splitting. For final buffing use a dedicated Concours towel instead of microfiber towel, Atopia has a great Concours towel. Microfiber towels with their prickly ends are really meant for lifting off dirt and removing just waxes and polishes. The Buffing towel should have smooth tufted loop ends instead of prickly ones. Speed not pressure.

The less you touch the paint the fewer the swirls.
