67 Charger restoration to begin-remove vinyl top adhesive from roof

I am starting my restoration on my 67 Charger. The original Owner had the dealer install a vinyl roof onto the car. When I purchased the car, the prior Owner had removed the vinyl top and did not remove the adhesive.

I have tried a few products from East wood with no luck. Has anyone used any product or tool



(adhesive wheel?) to remove 53 year old adhesive?

Or am I just going to have to sand it off?

See attached photos.
