Ford will warranty repair all of these problems. I had an issue with the door jams on my car having some bad overspray. And Ford said because it was not an "appearance panel" they would only cover half of the repair.
Whew, I'm glad I don't have these problems. I just enjoy the hell out of my Mustang.
She's not perfect, not the fastest, but she's mine and we have lots of fun, 140 mph rock chips and all!
We even pick up lumber at Menards.
