I was not sure I was going to like them at first but after having them on the car for a number of years I am glad I installed them. Lowering the windows a bit in the rain keeps the interior dry. Occasionally a spider will move in under one and claim the space as his own but that is the only negative point. They are stainless steel and dark painted on the underside. Most people never notice them. In fact they barely show up in most of my photos of the car. In this older photo featured on an internet blog, they show up the best.
