Sorry, but I can't answer your question adequately. I only had the Aero Vogue on my R52 for about 9 months before I sold the car. I remember them being quiet and working well. The vast majority of my driving is in the city or SF Bay Area commuter traffic (slower speeds). There must have been a few occasions when I used them in the rain at 70-75. No issues came up that caught my attention, but I can't give you a definitive answer. Also, I was using it in combination with Aquapel, which I have been using regularly for years.
