Doesn't matter how expensive the paint is, the determining factor is the preparation, and the skill of the painter.
If the painter's rhetoric outclasses his skill, then you will get a crappy job, if your car is painted at a VBRA bodyshop where they have their own mixing scheme, gas heated, floor level extraction booth, by an artisan painter who takes pride in their workmanship, then you will more than likely be happy with the finish.
Unless your car is something really special, I'd be tempted not to bother, unless you have stripped a car in readiness to be painted before, you are in for a treat................it takes many many many careful hours to simply remove the trim
