Rednsxe:
Depending on how bad they are, you can start with Meguiars #9 ver2.0 Swirl Remover OR 3M SMR (Swirl Mark Remover)
I've used both with a DA polisher (PC) or Meguiars (same unit) and a foam polish pad.
Just let the polish do it's work and clean up with some Meguiars Final Inspection in between each time you polish until your satisfied. Follow up with your Zaino Z5, which masks light swirls.
Once all swirls are gone, finish up with Z2 if clearcoated or Z3 if non-clearcoat. Follow Zaino instructions, if using ZFX with Z5 and Z2/Z3 you will not have to wait 24 hours between coats, again follow Zaino's instructions and tips found on the website.
