This is a great product especially for use on older wiper rubbers that have no cuts in them but have become stiff. This products basically makes the rubber very soft and smooth. One application lasts about 3-4 weeks with moderate rain. I found this to even work well on new wiper rubbers as most rubbers sit in the store for a while before they are purchased and can become quite hard and dirty.
I recommend this product.
