as alfisti said. megs QW is supposed to be allowed to dry, then wiped off. which completley defeats the purpose of a spray wax to me, if i wanted to wait, id just use a normal wax. but spray waxes on the other hand, like AW, and UQW (which are probably my favorites) get put on my car probably once a week.. i usually wash, then dry, then spray wax, most often with uqw... eagle ones nano wax, and wioe and shine are both good too, so is FX (which says it can be used as a qd or spray wax, but i only used it as a spray wax. my favorite use for spray waxes is for wheels though! i clean my wheels, then use a spray wax, which takes all of a minute or 2 for my fairly intricate wheels.. spray waxes might be my most used type of product.. i like to spray one spray per pannel (2 or 3 for a hood roof or trunk though) right on the pannel, then wipe with a microfiber until almost dry, then flip and wipe down with the dry side. sorry my response is so long.
