Just so you guys know, the "flat" look that is being painted on these high-end cars is not flat black, such as a primer, but is Satin. It is clear-coated just like normal paint, but using a different process and a different chemical make-up to bond to the paint. Therefore, cleaning the paint is identical, but I am guessing swirls and small scratches will be less apparent due to not being clearly visible by light reflecting off of them.
