Thanks for all the advice and the amazing Detailing Guide by Pb! Here is a follow-up on my progress. I taped my hood down the midde for comparison.
The right side:
1) Washed (Meguiar's Gold Class Car Wash)
2) Clayed
3) Polished (Meguiar's #83 Dual Action Cleaner Polish; Orange Cutting Pad; PC7424)
4) Klasse AIO
5) Klasse Sealant Glaze
The left side:
1) Regular wash (the white specks are polish splatters from the right side)
Its hard to see in the pic, but the right side is much shinier and all the swirls are gone. I started with the 6.5" white polishing pad, but it had a hard time removing swirls. The 6.5" orange cutting pad finally did the job.
Q: Pb suggested using a 4" pad and plate for heavy swirls. I have swirls. Should I invest in a set of 4" pads and matching plate? Or, will I be fine with 6.5" pads (on 5" plate)?
Q: Should I try a different polish? Something more agressive to make my job easier?
Now, I just need to do the rest of the car
