Nu-Finish, Simoniz Ice, Rejex and several others like them, all work about the same. Wax on wax off. Last a very long time. These are not waxes but are polymer coatings. The same thing the dealers will sell you you for hundreds of dollars in their "Protection packages" You can do the same thing for $10-20.00. I do mine once a year and it really holds up.
