I used the Mother's clay bar and there certainly was a noticeable difference in the smoothness of the paint before and after. I first stripped the car using dish detergent and even at that, the car looked amazing when the claying was done even without any wax on it at all.

Now, on to part II--use of 3M swirl remover (reccommended by Sal Zaino).

Then, fresh coat of Z1 and Z3.

Put on new wipers (again) that actually work.

Now, if I could just get rid of the two scratched wheels everything would be just perfect!!

 

I have my zaino clay bar sitting in my apartment, just waiting till my new house is done so that I will haev a garage to store the car in during applications .
I am sure the claybar will help get some og those annoying waterspots out.

 

I've had great results claying the car. I've done it only once so far, and I was amazed as to how smooth my car was afterwards. Just make sure you use a lot of lubrication.
