Did you have any trouble with the wing?
My grand am's CC seems to be soft as hell but the wing seems to be super hard. I had to hit my wing with #83x5 and #80x3 just to get all the swirls out.
I got so frustrated with it i almost decided to try and hide the swirls instead of fixing them. I then decided that that is NOT the autopian way and i NEED to remove them not hide them. So i worked on it for hours till they where gone. Man that sucked.
