Excuse my ignorance, what'* CD-2?
I forget what I used, but it was made by Gunk I think...had an orange cap. Works well with a toothbrush or wirebrush to get the details. I miss my old clean 3800 engine:
As far as tires go, again, I forget the name...but it'* a gel, purple in color, smells good enough to eat. It is the longest lasting tire shine I've used, resists water better than anything else in my experience. It'* not as quick to apply as the sprays of course, but it'* worth it.
You may get a little spin-off on your car, in fact, you WILL get some, but isn't really harmful, especially if cleaned up soon enough. I've found even with the sprays you get spin-off.
