I tried this product recently and do not like it for a number of reasons. I can tolerate the glossy effect well enough. But the major thing I dislike about this stuff is that even when being careful not to over apply it, and wiping the "excess" off, there is still too much of this product left in a state which can get on light colored clothing if one brushes against the tire. (maybe I didnt remove enough?) 2 Days later, I got a perfect impression of the sidewall lettering on my slacks while inspecting a wheel. It stayed wet, or gummy for a couple days I guess....
Oh yeah, I forgot, it has to be really carefully applied because it sticks invisibly to the wheels and is only evident when it picks up dirt.... :nixweiss
IMHO, If you are not careful with this stuff, straight back to the wash bucket you go !:nono
