A good ten euros for this spray that lubricates as hell and very slowly dries. Bought it for the bike and the tires. At first, after applying the rubber shines like new, but the stuff dries extremely slowly. On MTB stuff the entire frame injected at the first driveway full - well, carries also somehow to care for, I thought to myself then ... Who wants aufhübschen tires can access calm. All in all, still an expensive business - no more, no less.
