I bought my clay bar kit (made by Mothers) at a local parts store , A&A auto parts , but I've seen it at others like Pep Boys , IIRC . I gave about $16 for it & it worked like magic ! It brought an ultra smooth finish back to my '95 . It's not to tough to do , just let the clay bar do the work ... don't push down on the bar . It was well worth the price .
