Best protectant there is. Used it at strip mines on the tires of Terex Titans. Tires that cost $10 grand a piece. It prevented weathering,dry rot and was highly resistant to UV. I used to put it on the interiors and everything, especially the door seals and weather stripping, even the wiper blades. Not greasy, it is milky like original Armor All, but far better. I think even NASA uses the stuff according to the jobber that used to bring it in.
Their spray fabric protector is really great too. I used it on my cloth, canvas and nylon flags and camping gear, really prevented UV discoloring.
