I too think there has been a lot of issues with paint since the switch from solvent based paints to water based. The water based ones just don't seem as good. I had a friend who took his BMW back to the dealer on a paintwork warranty claim. He had, what can only be described, as orange peel starting to show almost like a bubbling and discerning differences in the paintwork. Anyhow, they rejected his claim and the service dept. even said 'It's due to the new water based paint and was a side effect so wasn't covered'
Bring back solvent based paints I say! (although that won't happen in the great(!) EU!!!!!! :/
