Thanks AZ Outlaws. I probably don't NEED to use the clay bar on the new car, but I do have a lot of crud on there from the dealer prepping - black lines that didn't seem to wash off. I always like to do the clay before I wax though because it makes the surface like glass before even applying the wax. But, I need my car to look good so it stands out come May 15 and we all drive up the CA coast.
