Posted this in the body shop area too but didn’t get any response. Not really Vehicle specific but I’m sure someone here knows what I’m asking.

Replaced the floor pans in the 67 Impala Convertible.

Now we have the floor ready for the sound deadener and then carpet.

What I bought was an ACC eva die cut sound deadening material, and a good quality ACC carpet with mass backing.

Question is, what is standard practice as far as spray on sound deadener (Lizard skin or similar) applied before the EVA? Would it add anything considering the materials I already have?

I will spray primer on the are metal portions before putting the other materials down.

I did not use that brand of sound deadener in my 67 coupe. When I had buckets installed, I pulled the carpet and jute backing, had the seats installed and then used dynomat. I honestly didn't notice any difference. I think if I did the roof and all areas behind the interior panels, that most likely would have been noticed. Of course, sound is subjective.

Thanks! I think the dynamat is Better than the stuff I have. It’s just like a thick tar paper material.

I may just prime it good and use the eva material and carpet. I have a roll of self adhesive sound deadener for the door panels. And in a convertible I don’t think much will help the road noise anyway.

I used Lizard skin heat/sound... it's spendy but easy...then in typical OCD fashion - I covered it w Dynamat....

Thanks! The dynamat is probably better than the eva stuff. I just bought it because it looked easy to apply being dye cut.

I got some super sonic material similar to dynamat for behind the door panels. Also I have mass backing on the carpet. Hopefully it will be good enough. The dynamat is just so expensive to use on the entire floor, and not sure it will do much on the convertible.
