One of my friend's dad is going to be painting my car the same color, Graphite Nightmist Pearl Metallic Code ZU. I'm not expecting the best job but atleast decent. He doesn't have a booth but a shop. I know about dirt and dust and stuff. Anyway, he says he's gonna do 6 clearcoats. Is this too much or will it shine better. Also, will quick drying clearcoat I guess still have a factory shine?
