Yes I hate the phrase too but there we go. I want to give the Roadster a proper clean and after seeing peoples results using clay bars I thought I'd give it a go, is it a case of you get what you pay for or is one bar as good as another? Are these detailing kits worth the money?
Try a friend of mine called Mark who owns and runs "More than Polish". Explain what you want to do and he will have the right product or will point you in the direction of the best.
