I'm assuming that the water spray test was on a vertical panel and if it was, I've seen the same performance from most other waxes.
I hate to be a killjoy on this but this wax appears to be nothing but a profit center for the company. Sure the car looks nice but would anyone be able to tell the difference between this wax and the same car with any of a number of other waxes that would cost a tenth of what this one does while providing 3-5 times the amount of product?
I'd be surprised.
There's only so much a wax/sealant can do and increasing the amount of money spent on the product isn't going to change that.
