I peeled some off but I’m thinking of using a heat gun,carefully applied.
you might try letting a solvent like a citrus solvent soak in for a while and then scrape with a plastic scraper.
I’ve been surprised by the effectiveness of citrus on adhesives.
Cover it with duct tape
DE-SOLV-IT a citrus based cleaner from wally world or Ace hardware works miracles on fresh adhesive, maybe if you let it soak it will get the dried stuff. Better than goof off or goo gone. I have never found it to hurt any finish though it will leave you craving oranges.
WD-40 has magical properties too if you really believe.
Don’t dismiss the duct tape idea to quickly though. It’s easy, relaxing and effortless.
Is it hard or soft ???
hard but flexible.
It is now soaking in Goo Gone. can't hurt.
or consult the internet:
According to Abby from GOOP Central (1-800-693-GOOP or 1-800-767-GOOP), there are three recommended solvents for GOOP. They are acetone, toluene and naphtha. Acetone will do a good job on GOOP that has not fully set. Toluene is a more powerful solvent that will remove fully set GOOP.
Works much better than goo-gone.
Read an MSDS
for toluene before you try using it. Very nasty stuff.
Naptha is not as bad but I still wouldn’t want it lying around the workshop.
Used a heat gun on low and most of
the Goop came off with some elbow grease plus some acetone.There is some sticky crud left that I suspect is contact cement.More elbow grease and Goo-gone today.
