Sound installation for interior, Experience and suggestions Options

[Mcraneiowa]

I purchased a couple rolls of Farman adhesive backed sound material with the aluminum foil top. Curious what everybody’s thoughts are for using this in the interior, on the floors and behind the back panel.

Thinking simply roll/press it down with a roller and then tape the seams. Are there other ways or material that people prefer to use as I keep thinking of the moisture that at some point will likely get under the sound insulation material even if I tape it.

FYI, I did replace the floors then coated entire floor top and bottom with Por15, followed up with paint so I’m starting with a very nice surface. I know I can put this down and will be fine for probably at least 15 or 20 years but I would like to think I could make it last longer so the next guy won’t have to worry about rust. Like to know what others have done and what their experiences are.

On a related note, and because this was brought up, I am a huge believer in liberally adding sound deadening to the doors. It makes the experience of hearing the door shut sound approximately $84,172 more expensive (+/- $40,000).

The only car that I didn’t do this to was my 1972 350 SL which came from the factory with bank vault doors.

Do it - you won’t regret it.

I used Eastwood X-mat all though the cabin. But didn't do the doors, (I ran out at the time) Next time I have a reason to open them up I would like to add sound deadening to them.

I have also toyed with the idea of adding some X-mat to the engine tins. Not where the cooling air goes, but to the bottom around the perimeter.
