What have the temps been for you lately? I notice that when I ran the truck out in the sun for a day, the paint always felt softer, or tackier/grabby to the touch. Next morning, after a night indoors, it felt quite dry and tough again. Perhaps it's an effect of solvent passing up through the surface layer from below?
I know that mine has wetsanded and polished out extremely well and is very difficult to mark or mar without really making an effort, say like dragging a high nail head accross it ( see expalanation in last posting )
