I have one of these Genesis cars too and it has been sitting in the box for at least 3 years as I have been afraid to touch it. :-[ (I know, that's probably the worst mistake of all!).
Jeff, may I ask, what exactly do you use for your washes? I've heard that some folks use stuff like windshield wash, alcohol (70% & 91%), glass cleaners, etc.... Regardless, some cars seem to want to repel water-based washes, even tho I've very carefully washed & rinsed them with soap & water. :-[
