Thread: hood liner

Tweet

Ok guys I need to make a hood liner for my 40 Ford p/u.
What have you used and how did last ect ?
I see lots of products but everybody says they make the best
your inputs are most welcome !

Wow am I the only one who thinks a hood liner is needed ? I'm thinking long term paint protection.

Never heard of anyone "lining" their hood.

It's actually not uncommon.
A lot of manufacturers use it as a baffle to reduce engine noise.
It's also used quite extensively on the firewall.

But I wouldn't know where to look in your country Navy.

Curious, what are you thinking of protecting the paint FROM? I'm with Mike, in the '50's OEM's put a Jute type liner in the hood, but I never really understood what value it added.

Most cars today have hood liners, they protect the hood from heat ( paint) and due some noise control. My 2019 Ram 2500 has it so does my wife's car.

Navy,
My 2017 F150 has a pad centered in the hood, immediately over the engine, but my 2005 Jeep Wrangler has nothing. As I've looked it seems to me that the main focus is sound deadening, to prevent the big, flat, suspended panel from resonating engine sounds back into the body through the hinge & latch connections. Looking at my truck & Jeep supports this thought. Ford makes a big deal about how quiet their F150's are on the highway, but JEEP says "Why"? It's a JEEP! It's NOISY!

As you look for info there is some mention of heat, even the combined heat of direct sunlight and engine heat damaging paint but I don't buy that argument. There was even one claim that the insulating panel is intended to melt in the event of an engine fire, extinguishing the flames! That makes zero sense to me.

I'd say for your '40 the distance between the engine and the hood will dissipate most, if not all of the engine heat, and the only reason to consider a liner is if you're concerned with interior noise on the road. I don't believe I've ever seen a street rod with underhood or firewall insulation other than the inside of the firewall, beneath the carpeting, but I'd probably use something like this - https://www.amazon.com/Abahub-Firewa...2718602&sr=8-7

Just my opinion and thoughts, offered for your consideration.

IMO, a hood liner is great for keeping engine noise from traveling up but horrible over the long term. They collect all the dirt and dust, varmints love to live there and build nests, and they hold moisture that leads to other problems. You could always spray a light bed liner or rock guard on the inner structure to protect it. Nearly every old fat fendered car or truck I've ever looked at didn't have a hood liner. I have seen some people that made stainless pieces and affixed them to the inner structure to add some shiny bits under the hood.

.

Thanks for the thoughts rspears and 1940 Ford Deluxe . Yes there's a bunch of space between engine and hood, I'm always over engineering things .

If you are worried about it I would maybe look into spraying lizard skin on it, they have one that is a ceramic coating for heat and one for sound deadening. Probably what will be going on my firewall and floor pan. I could almost fit a blower on the top of my big block and still close the hood so I don't see paint issues on the hood because of heat ever being a problem on a 40, my brothers car has no paint issues on the hood from heat with a 455 Buick and it was finished almost 20 years ago.

Thanks for the input FordyG, I guess the heat thing is not really an issue . The other issue I have is with the welds that show under the hood that I didn't address when I should have, now I've got to hide it somehow. Perhaps the lizard skin would help smooth this out.

I don't think you'll hide those easily! If anything they'll stick out even worse.

Maybe seam seal over the welds and try to smooth them out then spray the lizard skin over it.

Maybe a bit of body work would work ? Just wish I did it right to start with but I'm at burnout.

That's why hot rods always wore primer. Because as we all know, they aren't ever really done! If you are burnt from working on it, just get it into primer/sealer and then register it / drive it for a while. Then you'll probably have a greater level of enthusiasm and want to go back into it over the winter. At least that was my excuse! LOL... not really, but I do need to "re-do" some work on mine. And 1 more thing, after driving it in the real world... you will more than likely want to change some things, even just some little tweaks.. so finishing it NOW, may not always be the right road to take.
