I just detailed and polished my Race Red ST this morning. I don't see any thinness in this area, just a hint of orange peel, but no big deal in that area considering how it is positioned. Frankly, I think the paint on my car is pretty damn good; glossy finish, no bubbles or orange peel on the sheet metal or front or rear bumpers. It sits next to my Lexus IS350 in the garage and I was comparing the panel fitments between the two today and they have about the same gaps and alignment. I really can't complain about the body on my ST, it was built on a Wednesday so I don't know if I'm just lucky with a vehicle where people were paying attention mid-week or just luck of the draw. Or maybe a solid finish is easier to obtain vs. a metallic finish. For a car in this price range I can't gripe.
I laugh when people say there doesn't seem to be any QC at Ford these days. Most of the guys here are too young too remember the junk the Big 3 were turning out in the 70's and 80's. You think there are quality issues today, you have no idea how the quality today is exponentially better than the dreck Ford was turning out back then. My '76 Mustang was a complete disaster.....the lousiest paint job I've ever seen on any car and it was nothing fancy, just a solid white. And misaligned carpets and an a/c drain that always wanted to dump itself on the passenger side carpet, and on and on it went. It swore me off Ford, and American branded cars, until 2015. Even our lowly ST's are amazing pieces of equipment, mechanically, electrically and certainly in the reliability areas compared to the past. Keep it all in perspective, these cars are very well engineered and pretty well screwed together.
