I am writing this review after using the product for about a year and storing it in the trunk for another year. I'm not sure about other cars, but that's true. VW owners with V-Tex leatherette seats. I have a 2017 VW Jetta with beige interior and for about a year using this product on my drivers seat it has been staining my beige seat like hell. I have tried to remove the stains but they are not removed with ordinary detergents. I bought this product to protect my seats but ruined my seat instead. Please be careful.
