Years ago I used to use a product called Tannery Wash-n-Wax Car Wash for car washes during the winter months. It was a silicone car wash that left a pretty good film of silicone on the car as you washed it. Unfortunately, I see it's no longer made. Does anybody know of a similar silicone car wash product currently available? When you rinsed it off, the water would bead immediately as if the car had just been waxed. I tried several of the carnauba wash & wax products available today and none of them do this. In fact, they don't seem to leave any type of protection behind at all. Thank you.
