I'm enjoying my Wolfgang Black Diamond Tire Gel. It gives a really great look, NO grease, and lasts anywhere from 1 week to 2 weeks (with no rain, slightly diminishing look). I apply it with a foam applicator (the same kind that most people prefer to use with a paste wax). I find that this applicator has a low "nap" (since it's so thin), so the product doesn't just all "fall" down into the foam like an Eagle One Tire Swipe, resulting in less product usage.
I also like the Michelin Dressing, though. It gives a very nice matte look (just a little shine) on most tires, but doesn't last as long as Wolfgang, and is much thinner (where WG is a gel) so I use more, even though it's cheaper.
I really want to try Bold n' Bright though. Anybody who's tried BnB, what does it most compare to? From the pics it looks a little like Micheline, but they're just pics so it's kinda hard to tell....
Thanks
