I just finished "resounddeadening" my 85 245T. The Volvo foam was el shotto, stinking, rotten,etc. The Volvo rubber stuff, which is dense and pretty good was cracked and shot also. SO;

I tore everything out, seats, carpet, consoles etc.

It's amazing what I found under the carpet:

1) $5 bill

2) 1 french fry, tasted like Mac Dee's

3) Unused condom, honest it wasn't sex.

4) $1.57 in change.

5) Quite the assortment of screws.

6) RUST!!!!!!

I was ready for the rust, with POR-15 silver and black. That stuff is great. Follow the directions. Metal ready, one coat of silver and two of black on the rusty spots. Most other areas got two coats of black just for grins. That sucker is bullet proof now!! Miracle product.

Anyway I used two layers of the Jacque Whipme aluminized sound deadening padding stuff, followed by thick flat rubber floor mats on top of that all covered with the freshly shampooed carpet. Really got the carpet clean when out of the car. The flat floor mats where an inexpensive sound deadening layer....that I just thought of. They are available at any auto parts joint.

I treated the leather seats as well.

Bottom line: The car smells great inside AND it's a LOT quieter.
