Since you have a carport, you're better off than some others. As you won't be under direct sun, I think you could use quite a few QD's without problem, as long as you left the car out of the sun for a bit.
A couple that I'd suggest are Sonus Acrylic Spritz or if you're looking to just clean without adding any gloss enhancement, Spray and Wipe. Stay away from the 3M spray! (I did a review a while back on it. It's not as "versatile" or "accommodating" in the face of adversity as some others.)
