Hello, I have a bmw e60 limousine and have the following problem. If it rains again and again then the water on my paint does not completely drain away. There are lots of water pearls remaining on the whole car. I had once used a polish on it and sometimes in the washing box also a spraywax but the water residue would have to flow off the paint then or? You can now think the car has too many straight and angular surfaces so that water then nic It can flow off properly, but this is also the case on all sides, so not only on the roof and bonnet boot. Even if I drive with it remain up to a certain speed within the place the water remains available. Only in the garage or other covered areas the car starts to dry. Can someone help me? Zb neighboring cars are directly dry even without moving the vehicle. Would be very grateful about helpful experiences.
