I was just attempting to work through the logic.
The amount of space under the hood does not leave enough room for any realistic Rvalue, and most traditional engine compartments have too many other routes of heat loss for it to make a difference (by design).
While not costly, it will be as effective as doing nothing.
Even exotic materials that could make a difference wouldn't matter. Almost every item in the engine bay is made to dissipate heat quickly.
And as I noted (while not directed at you) if you use foil lined insulating under the hood, you will actually be losing the heat that comes down through the hood from the sun during the day, and its quoted Rvalue does not apply to heat coming out of the engine bay. The foil doesn't reflect heat back as many think.
