Abstract
A body that is adapted to contain a heat source such as a watercraft propelled by an internal combustion engine that is formed from heat sensitive polydicyclopentadiene. In order to protect the polydicyclopentadiene from deterioration due to oxidation caused by the heat, an insulating and protective layer selected from the groups of synthetic resins or synthetic rubbers is placed upon the polydicyclopentadiene at least adjacent the heat source. A preferred coating of epoxy resin is disclosed.
