  • Patent number: 5654055
    Abstract: A masking tape is provided that is suitable for insertion under many moldings and gaskets which not only masks the molding or gasket but also facilitates refinishing under at least a portion of the molding or gasket. The masking tape is constructed to include a longitudinal non-adhesive portion and a longitudinal adhesive portion, wherein the non-adhesive portion is stiffer than the adhesive portion and is sufficiently stiff to facilitate easy insertion of the non-adhesive portion beneath at least a portion of the molding or gasket to be masked while the adhesive portion is sufficiently flexible to permit the wrapping thereof around the molding or gasket. The stiffened portion advantageously provides a dual purpose of facilitating the easy insertion of the non-adhesive portion beneath the molding or gasket and creating a lever action during application between the molding or gasket and the wall or panel to which the molding or gasket is mounted.
