(I did call 3M and was told they make a goop remover but it's not
available locally and it comes in large industrial size containers.)

Try a local autobody shop supplier that handles 3M products (most all
do). They will have convenient quantities of 3M adhesive remover that
ought to do the trick. Give the stuff ample time to soften the glue
before scraping. Good luck.
