I don't have a carpet protection product and the 3M Scotchgard line is scarcely available over here in Europe. Does anyone have experience with the RainX product in this category? I was thinking of getting Gyeon Fabric Coat, but it's 4 times as expensive as RainX and, as far as glass is concerned, RainX has a great reputation for effectiveness and value. Any advice on preferred protection products for interior fabric would be appreciated. My upholstery is leather but mats and headliner are fabric.
