The heater assembly includes a case having a heating element therein, a channel extending through the case and having a size and shape for selectively receiving therethrough a first end of an elastomeric fixture outstretched through a substrate to a first length having a first width, and a heat transfer surface positioned relative to the heating element for receiving generated heat therefrom. The heat transfer surface is generally positionable relative to the substrate to cooperate with an adhesively bondable attachment coupled to a second end of the elastomeric fixture opposite the first end and including an uncured bonding agent disposed thereon. The heater assembly and attachment simultaneously sandwich the substrate in compression engagement in between when the elastomeric fixture extends through the substrate into the central channel and relaxes to a second relatively shorter length having a second relatively larger width.
