My Zaino order arrived today and I was reading the directions on how to use the Clay Bar. Now I thought I ordered sufficient compounds but I did not get Z-7. I got Z-1, Z-2, Z-5, Z-6 and the aforementioned Clay Bar. The instructions say to use Z-7 as a lubricant for the Clay Bar. Somebody please tell me what other material I could use as a "lubricant"? Blue Dawn? K-Y? 5W20? Any help would be greatly appreciated. Thanks, Tony
