Abstract
A method for applying an elastomeric patch to a polypropylene or polyethylene battery case including the steps of cleaning the surface area with a solvent, applying hydrogen peroxide to an abrasive material, such as emery cloth, abrading away the surface layer, and applying the patch to the prepared surface by means of a cyanoacrylate adhesive.

A method for applying a patch having an elastomeric mounting surface on a battery case or the like, the battery case comprising a polypropylene surface area, the method comprising the steps of:
- a. abrading the polypropylene surface area of the battery case sufficiently to remove a surface layer and expose the underlying surface of the battery case;
- b. applying hydrogen peroxide to the exposed, underlying surface of the battery case;
- c. after step b., applying a layer of cyanoacrylate adhesive to the exposed, underlying surface of the battery case;
- and
- d. positioning the patch with the elastomeric mounting surface against the adhesive.
