Question Hood insulation

I'm looking at putting some kind of insulation under the hood to make it look a little better and to give it some stiffness.
What have the rest of you done under the hood and to help the stiffness of these model hoods?
Please post pictures for idea's. I have the strips looking for a little more though!

Something like this.

Re: Hood insulation

I'm curious about this too.

While not all that relevant, I used a rubber mallet to get the original braces as close to the skin as possible, then cut my own rubber pads to slip between. It made a world of difference in the rigidity of the outer skin which used to flop around like a wet noodle running down the road.

I considered using something similar to what you posted and reshaping to fit, but everything I've seen so far isn't large enough, and would probably need 2 spliced together, possibly ruining the rigid structure it had.

Thumbs up Re: Hood insulation

firedemon,
thanks that is a start. I never even thought about them. Man $179.00 for that is a little steep. I'll do some more looking

Re: Hood insulation

Here's mine. I did this about a year or so ago and still looks good to me. Lowes insulation, GM spray adhesive and trimmed out with black foam weatherstripping. Came out nice a clean and gives the hood some support imo. Also added cross brace for stiffness.

Re: Hood insulation

why would you want to insulate the hood? that only serves to keeps the heat INSIDE the engine compartment?

not bashing, just wondering.

Re: Hood insulation

I was also wondering how insulation can add more "stiffness" to the hood?

Well not as much wanting to insulate for heat as it is to add some bling for under the hood at shows. I just don't like the way the hood looks when at car shows. Want to do something to make it look better.

Is the underside of your hood painted body color? I painted mine when I did it and I think that adds some "bling". It looks nice and is easier to clean up. I did paint my inner fenders and hinges black along with the core support.

Thumbs up Re: Hood insulation

Mine is all black under it. I did add the center peice to keep rain off the motor. I need to have it polished up good and that may be enough!

Re: Hood insulation

I haven't seen one or done it myself yet but I was thinking of spanning the distance from support to support with them meeting in the center of the support kind of like drywall on 2x4 and using some kind of tech screw or rivet in the support . I am a ways away from the point of under hood finishing touches though

You could spray paint a bowtie on that middle panel if you're just wanting to jazz it up a little.

Re: Hood insulation

I went with Dynamite extreme across the entire hood then added a Dynapad hood liner over the engine. VERY stiff. I'm very happy with the outcome.

Thumbs up Re: Hood insulation

Can you tell any difference in the temps under the hood? Does it seem to hold the heat in are is it about the same.

Re: Hood insulation

Yes, big difference. Reflects the heat well. The Dynamat has some thermal properties in addition to the sound deadening and stiffing properties. The liner is pretty much like any other. I certainly have considered installing over the entire hood but it works just fine like it is. I was amazed at the difference.
