Emblem Glue and Old Glue Removal

Not an A body, but I know there are knowledgeable body techs on here.
2007 Accord- the "Accord" emblem has come off of the trunk a couple times. I have used 3M trim adhesive, but never did it correctly. Meaning, I've never removed the old adhesive, I just added more, and it comes off eventually.

Is the 3M trim adhesive the correct stuff to use, and, how do I remove the old adhesive from the emblem, and more importantly; how do I remove it from the trunk lid without damaging the paint?

I will remove the wax.
