Abstract

A method for coating objects with silicone that includes the steps of preparing the silicone material; applying the silicone material onto a surface that is resistant to adhesion to silicone, such as an acetate film layer or the inside surface of an open air mold; allowing the silicone material to sufficiently cure to allow for bonding to an object; pressing the object against the silicone material; allowing the silicone material to bond to the outer surface of the object; and then removing the object from the surface resistant to adhesion to the silicone material.
