I found some 10 year old bottles of Natural Shine. I always used it on my interior back then. I figured I'd use this on my tires since I had no use for it now and much to my surprise this stuff made my tires look better than I'd ever seen them. On top of that it has also lasted longer than anything I've ever used. Anyone else ever use this on tires? I'm going to keep experimenting with this and see how long it lasts as I have a couple of bottles left.
