While searching for a tool that I misplaced, I found a can of Blue Coral Carnauba Wax. I'm not exactly sure how old it is, possibly well over 20 yr's, but when I popped the can, it was just as good as if I used it yesterday.
^^^^LOL! Almost had to use a hammer and a chisel!!! Especially after we used to put it on super thick, you know, for better protection and shine, then let it bake in the sun for an hour or so!!!!
