Is it okay to use leather care products, like say, Lexol (all 3- cleaner, neatsfoot, conditioner) on vinyl, like how the leather seats have vinyl sides/ backs? Will it harm, or just not be effective, or could it be good? If not, what's a good product for vinyl? And can I get opinions on Meguiars Natural Shine Vinyl & Rubber Protectant? I didn't see it here among their other products. Does it contain silicone? Sorry for too many questions, but thanks in advance.
