Agree with the posts above. The key is to buy a good quality wax and USE it. They haven't invented a brand yet that jumps off the garage shelf and applies itself to the vehicle. I find doing a section at a time works best since these beasts are so freakin' big. I have mostly meguir's products on my shelf, but another one to try is the new Nanowax, advertised to fill small scratches and swirls--just did my black 2003--no complaints , works great on darker colors, removed or reduced all the swirls/minor marks and scratches, and very easy to apply/remove.
