Sound installation for interior, Experience and suggestions Options

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.

After changing the floor pans. After owning the car 12+ years. After owning several old Mercedes-Benz. I decided I wanted my car quieter. Most people are worried about adding the extra weight, not so much right now. Engines can always get bigger. I installed the Eastwood version of Dynamats. It was done on all the floors and the back pad as well. Nothing has been added on the inside of the engine compartment yet, I wanted to spray a ceramic insulation on it. I figured Dynamats would just peel off due to heat. The doors were sprayed with undercoat on the panels inside where the bracing is. Then one sheet was slid over the door opening as the factory did with the plastic. Like I said it did not make it quieter it made everything duller. Made the doors sound more expensive and heavier. Would I do it again, yes. I would use the most advanced material that can be had. I just don’t know anyone that works for a major car company that would have access.
