I need help! Something ate the paint on my rims!??! HELP

Hi everyone. Quick version of what happened to me. I woke up and noticed my rims looked like they were spray painted black! I have a 2006 G35x sedan.

I had my friend look at it, and he say's that it wasn't spray paint, that the paint was actually gone. And it doesn't look like normal wear. It is in the shape of spray marks, lines, spinning from the inside, etc.

I had the compression arm on my tire and battery replaced the day before from an Infiniti dealership in Hoffman Estates as well as a wash from Three Oaks. Is it possible some kind of wash or fluid caused this? What could have happened to my rims.

I have attached pictures. Please help.... Thank you so much in advance.

Some type of acid has affected the paint for sure. The black is the base coat of the Hyper Silver color that was on the wheel. Your wheels are a 3 stage paint. Starting with black, then hyper silver, and finally a clear coat on top. If you are looking to get those fixed contact http://www.kwicksilversac.com/
