I buy it by the gallon and use it on everything. I haven't found any other detailer that compares. Just keep the vehicle dry for a few hours and as it dries the shine increases. I especially like Spritz on top of Fusion, Klasse and Collinite 845.
I want to add that after you clay and polish your glass try Spritz on it and you will be pleasantly surprised. I use DP High Performance Glass Restorer and follow up with Wolfgang Spritz and really like the results!
