Re: Best way to soundproof engine compartment?
You have resurrected a very old post but here is a link to the product I sell in Canada. I am not sure where you are located. The link is from Jamestown Distributors in the US. It is a high density fireproof foam in 2 layers with a mass loaded vinyl between them. It is covered with a foil surface and a which is easy to keep clean. It is sold with a mounting system and usually contact cement is used as well. It should be available where you are located. Hope this helps.
