Product name:
3M Automix panel adhesive...pn 08116 . Most any body shop can order a tube of it from their suppliers. They may even have a cheaper substitute as the dual-chamber tube is a bit pricey. You can also "Google" and get the full rundown on the product.
As for the heat factor...heat is generated by the combination of the 2 epoxy components as they mix at the nozzle. If you've ever replaced door skins and spot welded on the new one you'll appreciate the speed and durability of the panel adhesive. Locked on and sealed all in one step. Only down side is that seperating glued panels makes drilling out spot welds seem like child's play.
