My bike was already 2 years old when i got it, so even with hair dryer, the residue was stuck there (even after goo gone)
What worked for me was the wash/wax spray cans
You spray on there, leave it on for a minute or so and buff/wipe with a microfiber
Repeat until its all gone
Also worked on my car that had a 6 year-old sticker on it and the residue wouldnt come off even with lighter fluid, rubbing alcohol, (goo gone too obvious), was about to use a sharp razor on it and happened to get that spray on...
needless to say my paint is now thankful post-detailing
