I've had good results with Duragloss Aquawax (cheapest), Optimum Spray Wax (mid-priced), and Zaino Z8 (most expensive). The Optimum Spray wax beads like crazy and all of these products create a slick surface. Zaino Z8 offers a very glossy appearance while Optimum Spray Wax looks P21S-like...a very wet, deep look. Aquawax is inbetween in appearance. The old Meg's NXT and Eagle One's similar products are not as easy to remove, but they are easy to find. The new "hydrophobic" brands from Meguires look interesting.
