I think the only thing you're doing "wrong" is product choice. The paint on the Crossfire is extremely hard, meaning it's fairly difficult to correct defects. ScratchX is a very, very mild paint cleaner and as such I wouldn't expect you to accomplish much with it. Most of Adam's products, good as they are, are not terribly aggressive either. Depending on the quantity and severity of defects in your paint you probably really need to step up to something a good deal more aggressive.

Let's face it, if you aren't getting rid of swirl marks I don't care how often you're putting pad to paint, you just aren't removing much paint or the swirls would be gone. Unless, of course, you continue to put fresh swirls in through a less than perfect washing/drying process. That's where most swirl marks come from.

I fought the paint on my car for a while with a D/A buffer but finally just gave up and used my rotary with a wool pad and M105 Ultra Cut Compound. I don't recommend this for someone who's never used a rotary before but what I will recommend is you wait until after SEMA next week to make a decision on a new choice of polish/paint cleaner/compound. Meguiar's is introducing several new products at SEMA that are pretty amazing and should help your situation tremendously. They llikely won't be on store shelves until late December, but they will be widely available (think Wal-Mart). I can't divulge anything more than that, but trust me - there's some pretty amazing stuff coming real soon.
