hi have used it once, never again not for me (in fact i still have the tin if anyone wants it free). i keep all my bike in show room condition. so no real point in me using it ,i found out to my cost. i put it on one of my bikes and after the first ride i just wanted it off, **** was sticking to it and it just looked crap. took me about 6 hours to get it all off. I can see that if you use your bike all year round or just do not bother to keep up with the cleaning then i guess it will do its job. but for someone like me that will go out and do 250 miles, but then will do an hour to 2 hours clean when i get back then there is no point. as every bike i buy i use then sell for more than i paid for it,. as they are kept to a standard that is almost show room. if you keep your bike in top condition then i would not bother. but if your bike is a every day hack then yes i guess. just my opinion.
