Hi,
I'm from Malaysia. I'm looking for foams that can be put under the engine cover, wheel wells and firewall to absorb/block air borne noise. I'm planning to sandwich a sheet of lead (which can be sourced locally) between 2 layers of 1/8" of closed cell foam. My problem is,
I couldn't find a decent quality acoustic foam locally. Most of them seemed to be made of neoprene or rubber. Dynaliner, which I can buy
locally, feels very light and doesn't have the density to block noise. Please advice.
Thank you.
