I am from the WD40 camp. Solvent based wax and grease remover is #1. 3M adhesive cleaner #2. WD-40, third choice. Unless theres much buildup, then its WD after washing with soap. Never used GooGone. Nor Hoppes, on paint. I begin with rubbing alcohol. But if it is old, baked-on Florida duct tape glue... don't expect to remove all traces. If it dissolves with whatever you use, fine. If it doesn't, stop and leave that last bit of residue because IF it left a mark its real easy to loosen the paint if you keep on trying and rubbing. Also, if any residue does remain, do not attempt to polish or wax that spot. Go around. Just be gentle, clean it well first so you don't rub dirt in.
