Again I have to come to defend the honor of the clay bar.
you are the only person I have EVER heard of that had a problem with the clay bar. Please tell the folks here what you did, and by that I mean how you used it on your car.
Did you apply the clay bar with the cleaner or without. If you used it dry, which it sounds like you did, then you should try to read the directions. I have used the clay bar on four different vehicles over three years of use and have had spectacular results that no plain wax job can duplicate.
I would love to know what happened to get clay on your car in such a profuse manner.
