I've seen people recommend complete clay bar and wax treatments twice a year. IMO - this is overkill if the car is garaged and not a daily driver. Mine hardly ever sees rain and does not typically sit out in the sun. It's driven twice a week for about 60 miles. A clay bar once a year and wax once a year is fine.

What I do want to end up with eventually is a good porter cable tool and a nice set of pads. My car has tons of scratches that I'd like to try and buff/polish out. It's on the list for next year some time. Obsessivedetail.com has some good stuff btw. Good deals on MF towels. And an OK price on the porter cable tool.
