I would bet that 9 out of 10 products will contain petroleum solvents or petroleum distillerates? I have been using 303 Protectant. I like the look of the surfaces when I'm done. There smooth, not oily with what I would describe as a waterproof surface. Did the roof, rubber seals, plastic around the windows, and the front and rear cap. I guess time will till if one is that much better than an other. See-Ya
