I helped detail a friend's car yesterday and at some point, sat on a piece of Meg's clay. It stuck to me until I got into my Acura and sat down. I tried to remove the clay residue with HD UNO, 3D APC, painter's tape, and I even tried claying it away. Nothing has worked so far. I picked it down to a thin layer, but this thin layer won't come off. Anyone have experience with this?
