Quick follow-up. This guy crazy into is car...I love it. I feel like we've become friends I've been out so many times to detail his car...I even tried to teach him how to do it himself, but I guess he just likes having me do it. I probably come and and buff this thing every 3 -4 months...it's a solid 95% swirl-free at all times. Because he washes it fairly gentle-like, it never needs more than a 1-step...except for the first time when I had to fix what the dealership did.
