Good work. Keep in mind that Meg's uses a lot of filler, so things look REALLY good right after you apply the product...however, since even the swirl remover (if used by hand) is mostly filling in the swirls and not actually removing them (you need the heat from a PC or Orbital to effectively break down the polishing compound), they look really good right after you finish, but the swirls will 'pop' back up in a matter of weeks.
Best to go ahead and address the swirls with a PC or Orbital. It's not any more work than what you did, and you actually correct the paint rather than cover it up.
