to add something to your arsenal to address the swirl issue. If you are willing to try a decent dual-action polisher aka random-orbital polisher (like the Porter-Cable 7424), I'd recommend Meguiar's #82 Swirl Free Polish or #83 Dual Action Cleaner/Polish. They can be used by hand as well, but a polisher (not a rotary buffer - those are a different animal) would help immensely.
