Yeah, hopefully you can get away with a 1-step polishing (with a finishing polish) with a Dual Action polisher (like the Porter Cable or Griot's) at this stage, then seal the paint with something like OptiCoat/CQuartz Finest/Four Star Sealant etc. Or if you are a DIY'er, Collinite 845 or 915 to get you through the winter; not as shiny as sealants, but a bit more affordable. Seal the wheels too, OR use Plastidip to keep 'em protected. Wheels off would allow a more thorough job, if you are so inclined. FlyBy30 or Aquapel or some such product to seal the windshield the windshield. OC/CQF on remaining glass. mjhpadi and others can speak to what Adams products would work, they have a pretty solid lineup too.
Basically, wash, clay, polish, seal.
