Not with that one in particular, but I do have a bad observation from a similar product.

Scrathes - because they are to be sprayed on and then wiped, you are going to get scratches from whatever dirt is currently on your car. Put a couple of scratches on my Black G (I notice, but doubt anyone else would).

This weekend, I tried using a California Duster to remove dust (duuuhhh), and then following up with Mequiars Quick Detailer, and that work great to leftovers from recent rain.

With the detailer, I found it easiest to spray and make the initial light wipes with a cotton terry cloth, then drying and buffing with a microfiber towel. Looked Great!!

Bought a car care kits from Griots Garage last week, and should be able to wash this weekend. Will post results to the forum.
