Hello, have read all the articles on the topic of water-repellent discs here in the forum that I found. But the opinions are quite different, from really practically to worse than normal discs? I myself don’t have the mentioned discs/mirrors, but find the idea good. Now my question: There are different “wets” in the accessory trade with which a pearl can be achieved (allegedly). Do you have experience with products – what do they do and have the disadvantages? Is the te chnik the same as with the Volvo original discs? Thanks for your answers volvovolvo
