Get the G2 kit. I got mine from SWA (free shipping), and they also have them at tirerack.
Just painted mine silver last week and I love it

It isn't flashy or anything, but it looks really clean and shiney.
BTW, they say to use it within 4-6 hours or it will start to set up... Mine set up a lot quicker. I painted my fronts and then waited an hour to put the front wheels back on, but when I went to do the rears the paint was like a paste. It still looks good though. I would just suggest either completely lifting the car and doing it all at once. or just not waiting an hour to put the front wheels back on. Just be carful not to hit the calipers with your rims.
