I recall talk of excess heat within the engine compartment if you dynamat the hood.

sorry, should have been more specific.

I hear on good authority that you should NOT use a hood pad. The hood was made of aluminum specifically to dissapate heat; blocking the heat transfer is asking for trouble.

so, besides dynamty on the floor ( and the shop i went to used a similar product called ROADKILL) i've found taking the hardtop off reduces cabin noise significantly , and makes it more fun as well....

Using the heat logic, how does one explain the trunk lid and doors?  The hood is aluminum for weight on the "Sport Light".  Still, I would think dynamat would be a bad choice for heat and other reasons including the clearance over some points on the engine and weight on the spring.
