I have been using supershine for more than one year and i own a black R15. Black is the only colour which can easily get dirty and give a dull look. Well, supershine was the ultimate solution for my problem to keep my bike supershine always. Once in every week, i'll wash my bike and apply supershine to the every metal and plastic parts of my bike. To be honest ,after applying it,my bike just looks so dope and glossy. The main advantage is that after applying it,the dusts wont easily get settle on my bike. Eventhough if some dusts manage to settle on my bike, just a swish from a cloth will sway them away very easily. I am just a customer and this is a honest review for my most favourite product. So anyone,guessing to go for this product,just go for it without any hesitation. For sure your bike will look exceptional from other bikes in the road.
