I was wondering what if any clay do you use during your pre-waxing of your car? I have never used clay and am a bit skeptical,as seeing my dad has won several car shows without ever using clay. Does the clay really make that much of a difference? I would be interested in seeing what specific products you guys use on your boxsters,especially to clean the convertible. Any links to site that have good car car products would be helpful.
