Hello, for a good 4 weeks we are the owner of a Mercedes 180 CDI with AMG style in WEISS. Everything is great. However, it rains recently with us and we were aware that white is a sensitive color, where you can see the dirt simply faster. So so so far every 3 days the car with in wash box with water lance and cleaning agent radiated and made dry, and every 7 days 1x with shampoo, and 1x every 21 days and Sonax seal. Everything great and really top. However, we were on holiday now for 1 week. The car was cleaned before, parked on a protected parking lot with us. It had rained in the time and when we came back and saw our car, we thought we were not right. The car in almost all places as clean as before, but at the places where the rubber ends at the doors – A-pillar (window-canned) under mirror, B-pillar under the aperture, and rear cover looked that one had to be ashamed that the car looked like. a woman with make-up crying and really black broth ran down from these places. And not only a thin strand. No that was really equal to 5 cm wide, so that you could not really miss it. We saw it at first, but thought that would come from the highway ride in the rain. But now we are really horrified. How can that be, that a rubber leaves so much color in rain? And above all, what can you do about it a bit I mean, I already had a lot of vehicles, some in white, but never before did a vehicle look as unsightly as the Mercedes in the rain. Because I didn’t see such a black broth in a car when it was raining. Can anyone tell me how we can contain that? 1x every 7 days the car would be enough for me to wash honestly. Every 3 days it just goes like that (but because of the insects on the front that they can’t burn in the somme so badly). e it was the same again. Yesterday evening was cleaned, everything dried up etc. and the car turned off – this morning to the car, and since it had rained well the night, everything was for nothing…. Super Abperleffect from Sonax, rims 1A, etc. but really ugly black stripes on the paint … Would really look forward to help.
