Best stuff on the market. Been around for years, since the seventies I know because I have used it since then. Protects vinyl, car dash, even leather, better than anything else. Put it on rubber and on dash and not have to use it again for 6 months; even in the heat of summer. Best thing going. Does not give off a shinny glow but protects and has no drying effect of alcohol like some more known popular brands. Can't find a better product, I swear by it.
