2014 Cadillac CTS4 2.0T Luxury edition - black. 18" factory rims. Massachusetts. I have what I guess I would call hobby level + experience with detailing - although if you asked my wife she would say I spend too much time cleaning my car. I took a body shop class after work number of years ago to refinish my 1987 Chevy Caprice - which I sold. I always have questions when I am looking at how to clean this or tha t and I decided this might be a great resource.
