I had an old and worn out motorcycle tank pad (protector) and I want to replace it with a new one. It's too late to remove it together with the glue by heating it, so now I need to find a way to remove just the glue that was left behind (quite a lot).
As for most motorcycle question, the internet is full of different opinions. Using alcohol, WD40 or gasoline, to name a few.
What would be a minimal damage method of getting rid of that leftover glue? (I'm asking for a metal painted tank.)
