too hot
I've done several restorations on cars as well as a few glass rods.The hush shield and dyna mat systems are said to be for interior use only.Not sayin your car is glass but ever sit in a glass unprotected car?
LOUD. Cover all areas u can.Wheel tubs inside doors... there is a stainless and cloth type muffler heat shields in both bolt on and stick on apps. i order from jegs.The rubberized products simular to spray on box liners work well as well.(i've allways farmed this step out)but do make a do it yourself kit available at some big auto supply stores.
