I see both on internet pics, videos and at car cruises. On a non correct seasonal use street machine. Feel free to explain benefit of or detriment to.
Thanks.

Covers up the bad paint on the bottom of my hood
Pro: Noise reduction
Con: Mouse fodder
Con: Mouse fodder
Cons: gets dirty, can't clean, eventually will start hanging down and really looking like crap.
Mufflers are loud enough to mask any noise reduction the hood insulation might provide.

Believe it or not, another function of the fiberglass spun hood insulation is to fall onto a burning engine to help smother engine fires.
Exactly.. that and fortunately with my car it's also coded for one to do so. Car only got a hood pad with full undercoating J55 code.
I know mice like the JUTE sound deadening found in other areas, they feed on the hemp.
I don't think they'll EAT fiberglass hood insulation, but they may nest in it.

To answer your question directly, NO it is not necessary.
I have always wondered if that hood insulation wold not help the hood paint as it keeps away some engine heat?
Like said, it gets nasty.... and just ugly unless brand new.
Its just one less thing to spend $$ on!!

I wish I had done a temperature gun test before I installed the pad. Guess I could have done a db test also. I got the molded type.
Yep and it prevents the bad paint under your hood.
I wondered that as well about damaging hood paint from the heat. I also have painted fiberglass(?) hood inserts to think about.
Funny, most everyone comments about the bean counters scrimping on necessities for our cars yet few believe that the hood insulation is necessary.
If it was part of the factory undercoat option, I bet it was just a cheap way to add value to that purchase.
I do a project, I clean the bottom, the hard way as I have no rotesserie or lift, epoxy prime and paint that, and IF I think I will keep it long enough, I will undercoat it. NO I don't live in the friggin rust belt either. I will drive it and it would never go to the "dog and pony" show. lol

Another minor issue with the hood insulation is that it can rub off the paint on your nice new pie tin, especially if you have a thicker carb gasket.

Well that settles it for me. No under hood insulation. Just gonna paint the underside.

I always remove them.... and the half-century of dirt accumulation they're holding.
My 65 Dart wagon had most of the hood insulation when I received the car. So i replaced it with a reproduction.
It looks deluxe!
IIRC, it was an option. My car came with it, when restored it will have it.
As for usefulness... The OEM paint inside the engine compartment looks a teal in color. ( DD1 is light blue metalic ) heat from the engine changed the color, I imagine it could do the same to the paint on the outside of the hood.

Available with the full undercoat option, J55, as I noted above. MAY also have been part of the "california car" package for noise suppression, where they took away chrome tips, unsilenced air cleaners, added resonators and the likes...
I don't know if the option was offered pre 70. I know every Mopar we owned all had them. Is J55 on your fender tag?
