I've heard good things about the product from the DIYer crowd. Judging from the comments, it probably has lots of fillers (concealing abilities) and is fairly friendly to a variety of application methods.
Personally, in the past, I have never been a big fan of spray waxes. They've always streaked on me, or I have had poor durability. Or they've required a lot of follow-up buffing with a dry towel in order to remove the residue.
One product that seemed to change all of those complaints for me, was Optimum Car Wax. As long as I apply it to a cool panel (note: the label says to not use it on any surface that is over 120F), it does not streak on me at all. I usually fold a mf towel into quarters, and give the towel two sprays. Then I spray each 18"x18" section once, and use the "primed" mf towel to spread the product. I then immediately follow-up with a clean/dry mf towel to lightly buff off any streaks. Most people have also had ridiculously good durability with it -- I've only had mine on for about two weeks, and it's still going strong.
