Hmm, interesting. I think it'd be better to practice that on a scrapper first though! I'll stick to rubbing in some gel. I don't want to sound like a salesman, but it only takes 15 mins or so to rub it into both bumpers and buff it off. You can do other bits like spoilers, door rubbing strips, grill, door handles, window trims etc if you have more time.
I did find it faded a little after a couple days, and the first time I used the stuff I gave it another coat a week or so later. That was about two years ago, and since then I've given it two more goes. Once last summer, and once this summer.
You can see the difference, but it's not as obvious as when I used it first, it hasn't faded much in the last year. I use it as part of a yearly full car wash and wax.
Anyway, enough advertising, I don't have any business interest in the company, I just like their product
I'd have thought you'd have had at least something like this from stock:
