Earl, I would recommend that you air brush the stain. That way you won't add any more mass than is absolutely necessary. Start with an off white that is a close match and blend it in. If you can find an artist friend to do the work suggest they use designers gouache. It is very opaque and matte so very little would be required.
Have you tried plain old pure alcohol (the main solvent in brake fluid)? I've found alcohol to be able to dissolve/soften/de-gunk many of the old surround materials and glues, without screwing up the stuff you want to keep...
