That thing looks great!
As for your swirl marks, you should leave them be until you get some time to work on them in the Spring. You will need a polish to remove them. Polishing now would remove the LG layers that you have already put on. Sounds like the LG has filled and hidden them a bit, so just live with 'em til you can attack them correctly.
Don't bother buying a "cleaner wax," for two reasons:
1. A cleaner wax is not an abrasive polish and will not do anything to remove swirls or scratches; and
2. A dedicated paint cleaner (like Liquid Glass Pre-cleaner or Klasse All-In-One) will do a better job cleaning, and a dedicated sealant (like Liquid Glass or Klasse Sealant Glaze) will do a better job protecting and shining.
Definitely use clay, during your future full detailings (starting next Spring). Clay will
not remove swirls, but will remove bonded contaminants from the paint, preparing it for polishing and giving it a smoother feel and look.
Removing swirls and scratches by polishing is a whole other topic. In retro parlance, "polishing" was often referred to as "compounding." Today, there are much better products than the old Turtle Wax compound. But you have a whole winter to learn about that stuff. Leave the swirls for now, be happy with the LG protection for the winter, and read up over at
Autopia about polishes, machines and methods. That beauty is worth preserving!
