I do not use rain-x for the first time. The stuff is really amazing. Everything Else what you get in other stores, is just a tepid imitation. Rain-X is the only true. Who has ever driven a motorbike through rain, knows how annoying are spray and rain. But thus treated visor takes it all the horrors. The method of application is simple: A little of the agent on a "Zewa" so over the visor. The whole let it dry for a few minutes and with a dry "Zewa" over it to polish. Done. It is really very productive. First, the treatments keep some riding in the rain and you also do not really need much. My bottle held loosely by more than a year. In the times I have been a daily basis with the goat go. Even in spring, autumn and winter (really have gotten a lot of rain).
But unfortunately, I have to deduct a star. Not for the product, but for the packaging. The bottle is sealed in a plastic bag so that nothing leaks out of the package. Well wisely because it does just that. The bottle floating in their contents. The color of the sticker comes away already when unpacking. It's so easy, the amount for a treat lost, that's more than annoying.
Unfortunately, one gets rain-x nowhere in normal trade. Before, I got it at a major dealer of motorcycle accessories (are only 3 chains in Germany). But who is no longer in the program. That's why you have to willy-nilly order here and get angry about the packaging.
