I use a Carnauba Wax and it's called Blackfire, it's easy on and off and I buy it from Autogeek.net . I use it on my Tourag as well and you can get a year out of it for your car but I still do both 2x a year.
For my "TT" Roadster I use Pinnacle Souveran Carnauba every time I wash it and I wash it every time I take it out.

Great stuff! I use it on my truck everytime I wash it. I just bought some 303 but haven't used it on anything yet. Hopefully it is as good as I've heard.
