I must add this since I finally broke down and tried it, and OMG its simply amazing. The clay bars that they sell in auto parts stores in the was/wax section is simply amazing. The process is very easy to do also, I can honestly say it is simply awesome for taking out the rough grit/grime for your paint. Follow it with a wax job and you have a smooth as the day it was painted surface (almost). I think the one I bought was around $10-12 and should last 2-3 applications.
