I bought this locally because I had a coupon and it was cheap. I had been wanting to try a spray wax, and to be honest I planned on getting one of the more expensive ones, but for $4 after coupon it was too hard to pass up. I didn't expect much, and certainly not what it achieved.Application is about as simple as it gets, you spritz a few times over an area then wipe it into the surface with a microfiber cloth (immediately after a wash, of course). You don't need to drench the entire surface with spray; it spreads rather well, and three or four sprays onto a door panel was enough to spread across the area. As the cloth got wet with the solution, it began to streak a little bit, but the streaks disappear in a few seconds.Outcome: I noticed a nice, satiny shine, almost soft. It gives a nice silkiness to the finish. A nice shine I expected, as well as some water beading, after all it's a spray wax; what I didn't expect was the effect it would have repelling dust. Normally I use an auto-duster every morning, and sometimes in the evening. When I went out to my car the morning after application of the spray, I noticed it just didn't seem dusty. I knew it claimed to repel dust with its static properties, but I didn't put too much stock in it. So I skipped my morning dusting for the first time in a while. After three days I still hadn't used my duster, every time exiting my car saying aloud "how is it not dusty?" Seven days later when I washed the car again, the washing almost seemed unnecessary. A bit of dust began to settle, but not nearly as much as seven days without dusting normally would have produced. Update: I've noticed that during drier days, dust will settle a bit faster.Now, I park on a dirt/gravel driveway, under a car port (a roof, but open on sides). That's usually a guaranteed coat of dust daily. Five days after coating the car with Ice Spray I received a new CA Duster (my old one was shot). I actually put it in my trunk without using it. I'll probably try other spray waxes for fun, but I will be surprised to find anything that works so much better that it justifies the $10-$20 prices that some of them go for. This stuff works so well that the low price makes me feel like I found some secret. FYI the $6-$7 price is typical even at brick and mortar stores.So far as protection goes, I don't expect this to replace conventional wax/sealant, of course (update: actually, if you applied this regularly enough, it might do just that). All I can vouch for is the dust repellent effect and the shine, which I witnessed last almost seven days (note: I mean it reduces it significantly, not eliminates it). My guess is it also provides short-term UV/environmental protection, being that it contains polymers similar to the stuff found in conventional new waxes (I use the term "wax" loosely).Update: I tried applying a second coat for the first time today, with surprising results. I applied it one day, then the next day gave the car a light washing and applied the Ice Spray again. Wow. There actually IS a difference with two coats. The satin-y sheen is even deeper and more pronounced, and more slippery. This stuff is definitely not like some quick detailer. It produces a deep shine, it beads water very well, and if you wanted to, I bet you could apply this stuff once per week and it would be as good as standard waxing. I'm gonna test it out during rainy weather to see if it holds up.
