Clay Magic's my favorite clay bar. Since your car is new, I'm pretty sure that it's all silicone'd up by the dealer to make it look shiny. I'd reccomend washing it with something like Meguiars Gold Class Soap, or some other soap. All soap's are very similar. Dry with terry cloth bath towels. I would then polish it with a glaze such as Meguiars # 7 Show Car Glaze, and then wax it with something like Meguiars # 26 Liquid Wax. All these products can be found at Autozone, Discount Auto Parts, and some Wal-Mart's and Target's. Claybar's are good to use once a year followed by a swirl remover and then polish and wax. I usually wash once a week, polish every 4 weeks, and wax every two weeks. I use S100 wax. It's a Caranuba wax, so it doesn't last as long as some sealant's, but it puts out probably the best shine I've ever seen for with using a wax. Klasse, S100/P21S, Meguiars, Mothers are all good brands. Klasse is a sealant type of wax that lasts longer than a caranuba, but you can still top the Klasse with something like Meguiars # 26, or S100 and get an AMAZING shine. For swirl removal, which should only be done maybe twice a month, a buffer is definately a BIG help. 3M Swirl Mark Remover, Meguiars Dual Action Cleaner Polish, or Meguiars #9 Swirl Remover are all great products for that. They can all be found at stores like Pep Boys, and detailing stores. So here goes, one last time.

Wash - Once a week, quick detailer used right after drying helps the shine a lot.
Wax - For you, the casual cleaner, every month is good.
Polish - Once or twice every two months.
Swirl Removal (followed by polish/wax) - Every 6 months or so.
Claybar (followed by swirl removal/polish/wax) - Once a year.
