I have used the product for the first time today and have to say that the contents of the bottle very pleasant smell and I could even distribute it on `rubber after several unsuccessful attempts. ;-) One should advance necessarily very carefully read the instructions! The sponge - however applicator is scrap because it is already after first use flat as a pancake (keeps the mechanical stress just does not stand). I am already considering on how the next time I get the care product `s rubber. The company should make improvements here Sonax or the product an additional sponge - enclose applicator.
