If I use a wrap on a vehicle, can it insulate the engine compartment in a negative way, keeping more heat in? It is after all a thin layer of plastic.
Thanks and looking forward to your responses.
With no fans running and car not moving I can see a microscopic increase due to an additional layer of insulation on the hood. I will not be enough of a concern for me, unless I'm doing it to my jeep that idles extensively and sees a lot of low speed operation on large inclines. I removed the insulation from under the hood for that reason.

probably causes 10x as much heat to be trapped than the wrap.
So, if you are not saran wrapping your grille and vents, there will be no measurable difference.

It's usually cheaper than a paint job, but doesn't last as long.
Yup, thanks for clarifying. Dissipation
Yes, it will act as an insulator. I wouldn't expect it to make a massive difference unless perhaps the car was air cooled, sitting in Death Valley, and running at WOT while standing still.
