OK Kanundrum, maybe I was thinking of the dreaded sticky gooey Ferrari interior plastic finish? (You need Greased Lightning, not goo gone for that) But seriously the mild citric acid in goo gone is not going to etch the paint any more than bird poop would. Just don't leave it on there for a week. And don't take a week and a perfectly good microfiber towel to wait for your alcohol to work either. Microfiber towels are washable and reusable, when used with detail spray and wax. Tape adhesive, not so much.
Thanks, those are all good products I too would have considered using, plus WD40. The auto transporter was suppose to pick up the new Giulia today to deliver to me, but the driver refused to load it due to the hazy residual marks left by the packing tape. I'm noting this list of cleaning agents to the dealer for him to clean it up.
Take it straight to a REALLY good detailer and have them clean it, light polish and ceramic coat (or similar) it ASAP. Especially if you are buying and not leasing (with intent of turning it in in 24-36 months). If you are going to put a clear bra on it, do that BEFORE the ceramic coat.
