Best product I have used is P21S Gloss Enhancing Paintwork Cleanser, which may not be that easy to find (except online). If you want to be overwhelmed with information and ideas, check out autopia.org, probably the foremost detailing forum on the net...
And there's nothing wrong with using it after the car has been washed, clayed, and pre-cleaned (Mother's pre-wax cleaner works great for that step) as long as you follow it with a high quality wax, like Collinite's Insulator Wax.
