Under hood pad

[cursed avanti]

I need to install a new under hood pad. What type of adhesive should I use?

If you mean Hood Insulator / Hood Liner ... I used 3M #80 Adhesive  Spray.
I bought earlier the original styling material and lightly sewed the edges by hand so they don't come loose and hang. I also sprayed hole insulator with black spray.
I also bought a neat insulator for the future. They have ready one for Stude Avanti.

3M makes an adhesive for this application and headliners.  Super Trim Adhesive, product 8090.  Any auto parts store can get it.

Thanks Skip, that's what I needed to know !

I tried 3M trim and adhesive and my insulator fell off as soon as the underhood temperatures rose.  Then I tried Gorilla glue spray adhesive and again first hot day and after driving for an hour the insulator fell off again.  I need something that will hold the insulator in place in these extreme temperatures.

I used 3M #80 Adhesive Spray and works for me with original style full size insulator (from SI)

Did you use the HD adhesive, 3M number 8090?  3M makes two or three different similar products, but only the #8090 is designed to hold headliners and under hood pads.  Also, the instructions must be followed exactly.

I apologize. I misreported. 3M 80 is good for rubber and the like. I used German glue, which is intended for porous materials. I don't know if this is available in the US. Product is: Four Connect Spray Adhesive.
3M 8090 seems to be correct choice. "Aerosol contact adhesive designed for bonding vinyl tops, heavyweight liners and hood silencer pads where high strength and heat resistance are needed."

I used DAP Weldwood contact cement, available at Home Depot. I live in AZ where it gets pretty hot, and the pad has been holding on OK.

I was leaning towards trying Weldwood.  Thanks for the tips all!
