[0031] Turing to the construction of the tape, the base layer 22 can be made of a non-woven material, and preferably can be manually torn like a conventional masking tape. For example, such a nonwoven material could be a paper-formed material, like flat paper, creeped paper or other type of coated paper. Additionally, or alternatively, the water impermeable area can be formed by a water barrier layer 90, such as a coating forming layer 90 applied and connected with the base layer, or a liquid impregnated into the base layer to make it at least partially, and preferably near completely, water impermeable. Additionally, or alternatively, the water impermeable area can include a pre-formed film layer connected with the base layer, like layer 90, that could be located as seen in
[0032] In regard to the tacky adhesive layers, they can be formed from any conventional adhesive materials, e.g., pressure sensitive adhesive, always tacky adhesive, triggerable tacky adhesive, as long as the applied adhesive layer has the properties, and is applied in one of the configurations, as taught herein. For example, this commercially available paper and adhesive materials, i.e., tape, can be used when modified as taught herein to practice the claimed disclosure: PG21™ of Intertape Polymer Group® located in Sarasota, Fla.

Further, as an exemplary layer of material with a tacky adhesive layer connected thereto, the second or third tacky adhesive layers 50, 60 connected to the surfaces 30, 28 respectively, of the base layer 22 have an Adhesion Value of between, preferably from ten ounces/inch (Newtons/25 mm) to about forty ounces/inch (Newtons/25 mm)(but not limited to this upper end), more preferably from about twenty ounces/inch (Newtons/25 mm) to about thirty-five ounces/inch (Newtons/25 mm), and most preferably from about twenty-five ounces/inch (Newtons/25 mm) to about thirty ounces/inch (Newtons/25 mm), all as measured when separating the tacky adhesive layer connected to the respective inside or outside surface of tape 20 from the stainless steel panel surface in the Adhesion Value Test defined above.

Another step is adhering a portion of the width of the inside surface 30 of the tape 20 at the top edge 32 to the structure 10, as seen in the
[0035] As used herein, “adhering” includes at least some adhesive and that adhesive and the material layer to which it is attached has more Adhesion Value than a non-tacky area, preferably has an Adhesion Value greater than fifteen ounces/inch (Newtons/25 mm), and most preferably has an Adhesion Value no more than about forty ounces/inch (Newtons/25 mm). As used herein, a “secured area” and “securing” has at least some adhesive and that adhesive and the material layer to which it is attached has an Adhesion Value greater than ten ounces/inch (Newtons/25 mm), and preferably has an Adhesion Value of at least fifteen ounces/inch (Newtons/25 mm), and most preferably has an Adhesion Value of at least twenty ounces/inch (Newtons/25 mm).
