Call me crazy, but I find them kind of useless - to do one of my cars it takes about 25minutes (getting it perfect, meaning no streaks or hazing or whatever else).....always seem to be pulling my hair out, as it looks like I've wiped it all down, then look at another angle and sure enough there's haze leftover.
I usually end up pissed off and re-do it by waxing it with my cyclo, takes about 35minutes (and a perfect job with no swearing or frustration).
Maybe it's just me, but I"ve never had much luck with spray waxes and since it usually only takes me an extra 10minutes or so to actually wax it, I've always just stuck with waxing after my wash if I had to.
