I need to replace the door weatherstripping and am having a heck of a time getting the old adhesive off. I started to use Goo Gone but saw that it removes varnish. The doors are varnished (Spar Urethane)wood and indeed the Goo Gone was softening the finish so I stopped immediately.
I haven't been able to find an adhesive remover that won't damage the varnish. It also looks like some silicone may have been used for extra adhesion but I am not certain yet.
Any help is appreciated!
