Here are two option...
#1 is Meguiars Ultimate Quick Detailer. Black bottle, good stuff! Little pricey though! This product is great for doing a quick detail with, and it also leaves behind a bit of protection(wax). As you probably already know, you really can't wax that paint without it shining it up. This product will clean your paint, and leave a bit of protection behind without shining anything up at all!
#2 is the old fashioned way, and some old schoolers still swear by this. We actually used this method on a certain car at SEMA last year. WD40, may seem a bit primitive, but it works! Only problem with it, is it just doesn't last long, especially in the sun. Not sure exactly how long you'll get out of it, but I'm guessing about 2-3 days. This will shine the paint up a bit, but nothing that will be too annoying. Just use it like a quick detail spray, wipe it on, then use a dry towel to buff it dry. Do it in the shade or it WILL STREAK!!!!!
If it was my personal car, I'd go with option #1
Hope this helps!
