Don't confuse spray waxes with quick detail sprays. A spray wax is designed to be used just as a booster wax and should be applied to a very well prepped surface.

And applying 99% of products in direct sunlight will result in them flash drying - the surface of a white car can easily reach 130 degrees F on a warm day, a black car 170 degrees F on the same day. Big shock that a spray product will flash dry in those conditions. ICE may be an exception but get the MSDS sheet for yoursekf and look at what's in it, and how much. It's no wonder sales of the product are tanking.

As for an excellent quick detail spray, try Meguiar's Ultimate Quik Detailer.
