Well, I tried it out. I've used a LOT of different waxes and polishes over the years. Heck, I've got about a half dozen different waxes in the garage right now. And I must say, I'm very impressed with Rejex.
Goes on very easy, no problems there, and give it a 9 (1-10 scale.) Comes off pretty easy too. A light coat, as usual, is better than a heavy coat. If you 'clump up' a heavy section, it'll need a little elbow grease to get these white specs off. Overall, the better you put it on, the easier it comes off, I'd give it an 8.
Over all shine? A 9. The colors look really deep, and the shine is blinding! I put it on my chrome bumpers too, and they look like mirrors, literally.
The overall feel is VERY slick. I can see why bugs won't stick to it. Don't bother setting anyting on the hood, it's going to slide right off. Not that I would risk scratching the paint by setting something on it.
Cleaning factor has got to be a 10, better than anything I've ever heard about or used. Drove around for 3 days, and the rims have no brake dust on them, and it still looks great. I almost want to go out at night and hit some bugs, just to see what it'll do.
Overall flexibility of use, an 8. I like that I can use it on chrome and paint, but don't get it near black trim, or you'll get the white stains. I used it on the motorcycle too, hoping to keep bugs off the headlight and windscreen, which are plastic. Went on and off great, and really slick shiney finish.
The best thing to use it on is the wheels. Real shiney, and so slick, brake dust won't stick.
Downside? Cleaning factor, I'd give it a 2. Don't bother waxing if you have water spots or the like, because all you'll do is seal right over them, preserved in their natural state until this stuff wears off. I'd only suggest this for paint in really good condition. I tried it on some old painted motorcycle parts, and it didn't work so good. And the curing time is really long, and you're not supposed to put it over other waxes, because then it won't last as long.
We'll see how it stands up under time, but so far, so good. I'm really happy with it so far. I'll give it a 9, losing a point for sealing in a couple of water spots. Haven't seen yet how it beads water, but I've heard some people don't like that.
Shine is awesome though, makes all colors look really deep. I would recommend it to anyone living in a bug infested area, wanting a long lasting protective shine.
