If it helps, I stripped and painted my lower by the book and about half of it peeled off in sheets after one six hour outing.
Paint coming off in sheets is bad prep.
@alldodge has silver gear cases. this is a special $62 a can catalyzed paint. And special prep. Once you start, you have less then 6 hrs to use it up. This means the 4 coats need to be put on every 1/2 to 1 hr.
Mercury pays 3 hrs. So I could guess that some dealerships might skip some of what should be done.
Looking at the photos
@alldodge posted earlier with all the over spray, I will also guess they tried to do this outside and the environmental conditions weren't right.
