It's the hard surface gray areas. The right side of the console box, on the glove box, on the flat surface right behind the steering wheel. The black dash and door panels are not effected. The service manager promises me that their "touch up man" can take care of the existing problem. I have put my service manager on notice that I will stop using the Armorall on the hard surfaces but if the gray keeps rubbing off we will go back to square one with this. I mean the car is only 4 months old and I'm concerned what the interior will look like in a year. In regards to using it on the leather it has kept the seats in great shape. All my previous cars have had leather seats and I have always used Armorall on them. It not only keeps the leather soft but it also cleans any soil from dirty or oily hands and such. I originally used Armorall Leather Care on my Xfire but it seemed to leave a slight discoloration.
