Hi, got a 2010 WRX STi with swirl marks and a few light scratches, and a 2013 F150 Tuxedo Black and will be using this setup with the porter cable to keep them clean and shiny:glasses:
Lots of great information around here
you can even see the swirl marks in this photo.
crappy cell phone pic from first day i got it, its covered in snow right now :/
