Good waterproof protection against mud and dirt

I do not know how the dog owners would evaluate the product. But for parents with small children, the product is recommended. I bought it because our three year old daughter enjoys playing in mud and brings the dirt on her clothes and her shoes in the car. On the back seat have emerged over time a number of spots. After a laborious cleaning I bought this ceiling. So far, I am quite satisfied, the rear seat and the rear floor mats are thus best protected from dirt.
