The problem is mainly caused by the fact that the mud, when flushed from the curvature of the mirror's anchorage, smeams on the glass with the thread. As an option, the following solution is proposed.
It would take a rubber strip of 1 cm wide and one edge cut at an angle of 60 degrees. The stripes itself resemblades the blade of a box cutter. The striped shall be perpendicular to the mirror and exterior of the mirror on the exterior of the mirror and then stripping it under the seal of the door to make it approximately 5 mm. The water, the income before it, does not fall on the glass, but runs over the rubber band.
