It depends on the look you're going for, and how soon the vehicle will be driven.
For the Expy, I like to use the Meg's Hot Shine Foam and let it sit overnight. I hate the Hot Shine and NXT Insane shine sprays since they sling like no tomorrow (even after letting them sit overnight).
For other people, I think we use a wipe on product that leaves a "clean" look, plus, since it's wipe on, it slings less. I think it's from Detailer's Pride, but not sure...
