Re: [DML] Road Noises

There is a product that DuPont (at least used to) sell that is a peel and
stick gooey gray substance held together between pieces of plastic. The
installer just peels off one side and sticks the sheet to any clean surface
in the car. One of my old GM cars had it in the trunk over the wheel wells.
With age and heat some of the stuff would liquefy and run.

A DuPont representative said that the automotive paint division sold it, and
it was rather expensive for what it was. He told me of a demonstration that
they would do by sticking a 1" square piece of the stuff to the bottom of a
gallon paint can. He said that the sound deadening properties were great.
It is useful to stick inside of doors between the inner sheet metal and the
impact beam since this is a difficult area to get a good coat of rubberized
undercoat applied without dripping it everywhere.

Before the moderator kills this thread, I'll tell you of another
soundproofing job I did to a stainless steel sink. Hey! It's soundproofing
stainless, so it applies to this list, don't it? I used a can of that
expanding foam insulation sold at home improvement stores. I applied a
series of 1/2" thick beads of the stuff to all the under surfaces of the
sink. As it hardened, it made a uniform 3/4" thick layer of foam
insulation. Before I did this, the sound of water resonating on the bottom
of the sink would drive me nuts. Afterwards, the sink was very quiet and
kept the water nice and warm to do the dishes. I've thought about putting
this stuff inside of cars, but it would be very messy unless you had a lot
of room to work. In fact, I'm considering applying this stuff to the inside
roof of my Delorean while I'm replacing the headliner. It would sound proof
and also keep the car cooler -- a big plus in Florida.
