Mothers Car Care sells something called a Clay Bar Kit. It comes with a little yellow square of clay, some "detailing spray," and some wax. The clay bar is used to strip off everything down to the clearcoat, including the tons of layers of wax and all the crud sandwiched in between them. Wash the car first, then use the clay bar, then wax it right away, as there will be nothing protecting the finish after that. I used water instead of their "detailing spray" because I could just run the hose over the part I was claying (?) to make sure it was lubricated (If it isn't lubricated well it strips off the actual paint too). The kit costs about $17, but I got away with a free bar from a damaged kit. Score. My 15-year old car is shining more than most of the new cars on the road. <A HREF="http://www.mothers.com/">http://www.mothers.com/</A>
