I own a 2014 GMC Sierra with 10k miles on it that I bought a month ago. When I negotiated with the salesman I asked for the frame to be sprayed. They told me it would be. On the day I picked it up it wasn't done and they wanted to charge me if I wanted them to do it. I said I did wanted it done and the salesman said it would be taken care of. Looks like they sprayed the undercarriage with black Rustoelum. I should have expected nothing more than that. Complete mess, all over the wheel wells and suspension parts. I took a mild brush and was able to clean up most of it, but totally lost faith in the dealership and believing that they really want to help anyone anymore.
