Adhesive removal

[Pat, Andrea & Theo Quinn]

Well I have messed up my car. A piece of the door molding was loose, I
peaked under it and saw it was only held on by adhesive, I imagine much like
the emblems. I went in the house and looked through pictures of European
models which seem not to have any molding at all, or very little.
So I pulled the loose one off, and then spent the next hour trying to get
the adhesive tape off, what a mess! Does someone know what to do? If I have
to, I will reinstall the molding, but I will still need to get the old tape
off first. Help.
