I've been reading about detailing clay and polishing my car because it looks like crap right now and I just can't afford a new paint job. I went out and about today to find some of this clay and had no luck. I went to Wal-mart first with nothing. Then, I went to the major car parts stores around town and had no luck with them either. I went to Napa, Auto Zone, and Shucks. They had all the polish you could want but no clay. Do they hide this stuff behind the counter? Am I going to have to order this stuff online and if so where? Thanks.
