Hi
Its not the water based paint thats the problem - its the laquer process. - The clear coat laquer is still solvent based!!
The problem is that they are using more hardner in the laquer than before to increase through-put, it dries much faster and hardner is cheaper than laquer hence the mix is cheaper. also takes less time to dry (all about cost) - the problem is the laquer dries much faster which leads to it not flowing correctly hence the orange peel seen on most new German cars. (unless they get detailed of Course
As for the car looks spot on
