Abstract

Method of applying a heat activatable covering (24) to an area of a substrate coated with a heat sensitive coating (14,16) that has a melting point or a softening temperature lower than an activation temperature for the covering (24). The covering (24) is maintained in intimate contact with the area including a portion of the heat sensitive coating (14,16) while this portion of the coating (14,16) is at the above mentioned activation temperature. Before or after applying the covering (24), the portion of the coating (14,16) is heated to at least the activation temperature while the coating (14,16) has a heat resistant mold structure (22,23) applied on it, at least adjacent the portion of the coating (14,16).
