Question about z tech. Been reading a lot on undercoatings.and rust inhibitors. Found this z tech and it seems to be the stuff. Won't chip or crack like others because of How it's made . wax or something, can't remember right now. Guys saying used it once and every vehicle they had since then, u can touch up if need too.got an 81 dodge step side and 78 cj I want to keep and am thinking of using it. Anyone with use or knowledge of this product help would be greatly appreciated. Thanks
