I have a black GMC Sierra (with Zaino) that was very clean this morning until I got home and noticed small greasy spots on the tailgate and left side of my truck. It looks just like grease from tire shine (i don't use tire shine) on the side of paint except it doesn't wash off, and it will kinda smear. Some areas on the side of the truck are fine lines (look like spider webs), but when you touch them you see it's the same greasy mess. I tried spot washing with Z7 car wash with little effect, but the Z6 quick detailer with a little soaking and scrubbing took it off. I hate to scrub the whole side of the truck. Anyone have any suggestions? I've thought about trying a claybar, but not sure if this is the best route to go or not. Thanks in advance.
