So I recently bought a black 2011 G37S coupe about a month ago, but I received the car 2 days ago from Dallas. The rear bumper needed to be refinished before I took ownership of the car and I had my dad keep the car for a few weeks before shipping it to me in Utah. I'm wondering if the dealership attempted to "detail" the car before giving it to me and may have caused some damage because I didn't notice these hazy marks at the dealership when I was shopping around. I'm worried about the seriousness of what this is because although the car is used, it's new to me! I'm the third owner of the car and have no idea how often it's been detailed and/or waxed (if at all). According to CarFax and Autocheck it has not been in any accidents either -- but I know they're not 100% accurate. The areas in question feel dry and rough. I'm praying it's not clear coat failure or I'm going to be pissed!
