Underhood insulation

I have a '57 98 convertible that needs hood insulation. Does anybody have any photos of an original or restored hood so I can see what the finished product should look like?

Here is a photo of what the stock insulation looks like for the 57 Olds.

And here is a link from Fusick Automotive of a brand new insulation for the 57 if you are looking for a new one !

Hope that helps

upon further research I found more photos that show a 3 piece insulation. so that may be what the stock piece looks like.

here is one photo I found

I bought a new hood pad from Fusick but did not install it because it looks terrible when it gets dirty.

Yeah, that is one reason why I dont run any insulation on my 53.

one option could be to spray paint the insulation black or something.

That three-piece install looks like it makes the most sense. There is still a little bit of original insulation under those V-shaped braces on my car. I believe that the stuff that Fusick sells is the correct color(yellow).

I have the engine compartment in my '53 cleaned up very nicely except for the bottom of the hood, I don't care for the original fiberglass type of hood insulation, it tends to get pretty icky in time.
I am leaning towards either a spray on material like Line-ex, Rhino-liner or a foil faced self sticking product, I have used both on hoods.
I am in the process of removing the original jute, asphalt based installation from the floor pan in my '53, going to install Road-Kil. Wm.

My 57 had the insulation as one piece that was between the hood and the braces under the hood. I’m not, however, completely certain it was the original factory installation.
When it came time to replace it, I tried the Fusick insulation but:
a) it was too thick to easily fit where the old insulation had been
b) it shed a ton of yellow dust all over my newly finished engine and engine compartment despite blowing it thoroughly with an air nozzle

So I decided to go without it. Looks much nicer without it too!

I am concerned about looks and function, that is why I am leaning towards a more modern type of insulation on the hood. Wm.

Thanks for the note on the Fusick insulation. I steered clear of that stuff and went with hood insulation from Rubber the Right Way. It's gray and about 1/3 the price of the Fusick material. I also picked up some decals for the air cleaner and a couple other spots.

1957 Oldsmobile hood insulation

Here's a photo of what I ended up doing. There was insulation underneath the support frame for the hood so I placed the new insulation in those gaps, rather than over top of the frame.

Did you just unbolt and drop those two braces and slide it in there? Did you have to use spray adhesive or? Thinking of doing this and like this one better than Fusick's yellow one.

I just made cardboard templates that allowed me to push the insulation up against the braces. Removing those braces would be tough. I used a spray on 3M adhesive and it worked like a charm. The templates were harder than I expected. Those braces have a slight curvature.

Thanks Richard. I know those braces are bolted at one end and welded on the other. I figured it would be difficult. Yours looks great and i like the material better than the yellow. That 3M spray is good stuff. Thanks again. Mark.
