Gary, I got the G2 kit at
http://store.dragracing.com/product....2200&catid=101 since they had a really great price and FREE shipping! Gotta love that. Prep time was pretty quick, but then again my car only has about 3000 miles on it, almost all in nice weather. Not sure if that makes a difference, but they didn't look all that dirty to begin with! The kit comes with a spray cleaner that does a pretty good job. You might want to hit it with a stiff brush, but that's about it.
