The brand name Turtle Wax has been around longer than I have. Its name isn't synonymous with quality in any of the detailing circles I've been associated with for many years. In fact, Zymol that one can get at WalMart isn't the German Zymol and is actually made by Turtle Wax. If I were to suggest a product that is easy to use, relatively inexpensive, demonstrates very good durability and has a very good shine: Meguiar's NXT 2.0. The protectant is sold as a paste or liquid. An NXT booster (between washings) is also available as well as a relatively new product Meguiar's Ultimate Detailing Spray which comes in a black spray bottle an excellent product IMHO. I do not recommend the regular detailing spray which comes in a maroon/burgundy bottle. It isn't worth spit.
