I've used Zaino, Klasse, Zymol...pretty much all of them. The best "off the rack" one that I've used and is easily found is Meguiars NXT wax. I would clay bar the entire car 1st though. Goes on easy, comes off easy, shines very nice and is available at Canadian Tire and other places like that. I think ultimately you can get a higher shine level with Zaino or Klasse, but you do need several different products and a few coats. Zaino and Klasse also seem easier to work with if you have a polisher ( I have a Porter Cable 7424) whereas I have been impressed with NXT even when applied by hand..
