I think I'm going to go with the Meguiars Gold Class / S100 combo. Both products seem to deepen the look of the paint well. The down side is that neither product is particularly durable. The paint sure looked deep after I clayed then attempted swirl removal by and with Meguiars Scratch X, then put Gold Class and S100 on. My only concern is that the oils in Gold Class won't allow the S100 to stick, but hey, it can be used over glazes, so why not a simple wax like GC? When I first got S100, I applied it to the front fenders and the hood. This is when I attempted swirl removal on the front fenders. The fenders recieved GC and S100 while the hood just recieved S100. I realize that the hood gets quite a beating from the sun on my daily driven, un-garaged car, but I think the GC/S100 that actually lasted was worth it. The hood seemed to be less slick and not bead water the same way the fenders did. I'll have to do further tests when I have time to determine more closely what I'm going to end up doing.
I think a cleaner wax/s100 combo would be good, especially if you use the cleaner wax more as a cleaner and the S100 as the wax. If you don't get time for the S100, you aren't SOL either, as you might be with a pure paint cleaner.
P.S. the cleaner waxes I have are Zymol Cleaner Wax, Turtlewax Finish 2001, and Meguiars Gold Class. (all are liquids) so I'm in a similar situation as you.
