Duragloss Aquawax. Wash with your favourite soap, rinse, spray Aquawax while the car is still wet, then dry with a waffle weave towel. Aquawax is inexpensive, easy to use, looks great, smells great. If I had to pick one detailing product that I could not live without Aquawax would be it.
Aquawax, Prima Hydro, Wolfgang Spritz Sealant, Pinnacle Spray Wax, CG's V7, 1Z Spray Wax, and Sonax Brilliant Sine are all very good and "slick" like UQW.
