Replacing engine compartment insulation
 

1979 SC. Engine is out for other service items.
I ordered the factory engine compartment insulation. Any tips on what type of contact cement to use? Other lessons learned?

I'm not sure why everyone gets so pissy when someone posts a question that's been asked before... but yes, if you search there are numerous answers to this question. 3M makes a great cement for doing engine compartment liners.

3M spray works well. Actually I just replaced mine and didn't need any adhesive at all to get it to stay up/in place properly.

Pretty simple process. Clean the surface, getting all the loose junk off. Then dry fit the pad, skin side toward the engine. Once you are comfortable with the fit pull it out and get ready to glue. Use 3M trim adhesive around the perimeter and form a big X. It is also good to put a bead where the pad makes a big bend. Then use some 3M spray adhesive on the whole piece (this is all on the reverse side from the skin. Position it carefully and apply pressure to assure adhesion. You are done! And yes it does reduce sound in the cabin.

Howdy,

I had my upholster sew up a insulation pad for me, we used a closed cell 1/4" foam under a shiny silver vinyl, then I used an industrial strength Vel-Cro have attaching. So far it's worked quite well...

I was more interested in cleaning up the firewall, than sound proofing. Also the factory insulation will decompose sooner than later so while it's not "factory" I think it will hold up longer.
