Hey hey! I have a 2008.5 Crystal Pearl White MS3
The AccessPort is definitely nice, but I'm working with my sponsors to using the ProEFI on my car (PowerLab Engineering are doing first test fabrications of their turbo kit on my car).
Back to the topic: I hear I only need to really clay about 1-2 a year. I just know that I should clay it to get that shipping contaminants off the car before it's more than 2 months old!
Going to use Mother's Clay Bar with the QD then re-wax with maybe 2 coats of NXT 2.0. Unless 2 coats is overkill /shrug (then I'll use the Meguiar's Ultimate QD for post-washes)
