Okay, I'm posting this thread and my face is about as red as a ketchup bottle. I'm working on a black 2004 acura TL. The paint is coming beautifully except for some stubborn sap all over the flats of the car. I tried claying, nothing, rubbing alcohol, nothing, bug and tar, nothing. I've polished these areas and the surface is smooth as glass, but the sap marks still remain. I'm afraid that the sap was sitting so long on the surface that it is actually etched into the paint. Should I try a body solvent? Any other wonder chemicals you can think of that I should try? I would hate to send this back to the owner with sap marks everywhere, but now I'm thinking there should be an associated cost with the labor involved here.
