Add one more to the clay bar list. I too, used the Mother's kit.

I never used a clay bar before but after reading all the raves, I had to try it for myself and I must say, I'm very impressed. The car is smooth as silk and it wasn't nearly as difficult as I thought it would be.

I just wish it could have gotten rid of the acid rain marks. They are only visible from the right angles, but I know they're there.
