Have just taken delivery of a new Audi A5 (nearly part of Porsche) and was amazed at the difference a clay bar treatment amd zymol wax made to the appearance. Would not have believed it and have not done this to my new Porsches. The clay bar pulled out an amazing amount of dirt and what looks like preparation wax. I highly recommed all those of you taking delivery of new cars to get the treatment.
