Great Product
Used a total of four cans on my 96 Cobra. I did the floors and trunk after I gutted the interior panels to dead out some road noise. Worked great for me. A pointer that if you have drain holes in the floor or trunks make sure to seal them then spray, if you don’t the road noise will still be evident.

I Guess it Worked???
Used this to spray the liner of my wheel wells. I had enough to do the two front liners. Will probably need 2 cans per liner. Not a night and day result but possibly a slight less road noise in the cabin. If anything I think it made it seem like the back was louder but maybe that’s cuz it actually worked. Didn’t use a decibel meter before and after so can’t say for sure it’s doing what it claims.

Sprayed on evenly and flexible
This is indeed the heaviest spray can I've ever held so its got body ... I used this on the under side of a plastic engine splash guard ... the original splash guard was made of a more sound proofing material but kept dropping because of its weight. I liked the idea of plastic but didn't want any excess noise ... so I roughed the plastic shield up and gave it several sprays over a few days. It sprayed on evenly dried flexible and by all means should definitely help with the noise. The extra left in the can I'll spray on other areas underneath my car to help with any road noise as well. Will update if I have any problems but the application went on pretty decently.
