I just tried AIO on my car with 4* UPP over it, and it looks better than ever.
I currently use NXT Tech Protectant on my tires. I think it looks great. The only thing I don't like is that when you rinse the tires during the next wash, the oil from the dressing gets all over the driveway. I've since learned that wiping off the excess product upon application will prevent the oils from running off of the tire. I'd recommend doing that if you use the NXT T.P.
I know your frustration of trying to get a light color car to shine like a dark color! Good Luck!
It takes time, but don't think light colors can't have good reflections!
BTW, the above pic is with GEPC/EX-P x2/Paste Glaz.
You can see more results from my car with Gold Class (last year...2nd pic on homepage) and GEPC/EX-P/Paste Glaz on my homepage (near the bottom).
