The amount of heat exchange between fins and air depends on how much air flows over the fins and how fast. The amount of drag produced by fins depends on the same. In this case, fins would be counterproductive.
I think the hood would be the best large area surface for heat exchange. The warm air coming off the hood would help prevent fogging and icing on the windshield.
