ZaneO, The prep work I did was to unprep what they did. Although the car looked very good when I got it.....They did do a nice job with it. My prep was easy....Wash, AIO, and Z2x2..... Scott, I was very surprised that they let me do the car there too....That liability thing is a huge issue. When my client called me and said that he wanted me to do it at the Dealership....I point blank said, "I don't believe you." Fifteen minutes later The GM called me and welcomed me to detail the car there....he also asked me if I would need anything from them. Thier detailers were very gracious and asked questions about technique and what I charge for services. Like I said before "It was a quite an experience." I hope to get more work like this.....It sure beats working in driveways & parking lots. Oh yeah, The front nose looks a little different due to a friend of mine applied Ultra-Shield to the nose and mirrors....He did the work at his shop though.
