Hood insulation installation - 3m tape?

[KiwiWagoneer]

Hi - what's the best way to put this stuff in?
Guessing there is some wide automotive grade tape, that won't fail under heat.
Cheers,

The factory used a spray on glue, similar to the yellow contact adhesive for carpet and such. probably the same actually.

3M has it in spray cans and it seems to work good.

i can confirm it was yellow from the factory.
i have removed OEM insulation from 2 wagoneers
1988 and 1990
you could tell it was sprayed in a wide pattern
and it was indeed yellow.

i am using dynamats hood liner.....
not OEM but better in my opinion

once,...some old fuzzy OEM insulation was hanging down, my carb back fired and the small flame from the carb ignited the OEM insulation.
i did not think it was flammable but the fuzzy strands did burn.

so i think the foil face on dynamats product is nice...for several reasons.

I have been looking at the dynamite type hood insulation. Let us know what you think after installed. I really wish they would have the stuff in black though. I don't like too much shiny!

Contact cement sprayed with a primer gun is the proper way. It's often referred to as gorilla snot.

Locally and cheaply, get a $15 gun from harbor freight and a container of Weldwood contact cement from the hardware store. You can use the same for headliners and carpeting as well.

3M spray adhesive works just fine.

Remember kids if you spray a nice heavy coat of contact cement on both the hood and the_____________ (whatever you used here), go take a 10-15 min nap, then come back and push the two together, boom! your done. Ajax wont take that off..

[Probesport]

^^^ Absolutely. I also spray a thin coat after the wait to active and make positioning easier. Nothing will separate that bond.

the one I used already had an adhesive backing.
I will see if I can find the link and post it below.

This is what it looked like along with the LEDs I installed.
The product was called:

Dynamat 11905 Hoodliner 32" x 54" x 3/4" Thick Self-Adhesive Sound Deadener

This is what it looked like...

Please check your PMs.

I was debating using some of the asphalt sound deadening material and reflective insulation. I was mostly worried about heat loosening the asphalt and all of it dropping onto the engine while driving. Anyone have any experience with the heat loosening the glue?

I use Pliobond for heavy duty gluing. It is better than weldwood products.
It is also gas, oil and wind proof. Follow the directions exactly. The max strength is obtained in 7 days. Something to keep in mind.
If you want to glue a rock to a piece of glass. This is the glue for you.

I wouldn't use the asphalt based products under the hood. They are not designed to go there and are typically very heavy. I suspect they are also flammable . Go with the stuff that is designed for engine bay.
