Re: [Chrysler300] Carpet padding thickness?

Hi Ray,

You're on the right track. Starting with the Dynamat is a good move. I am very pleased with how professional my 300C floor came out - in spite of the fact that I'm the one who did it. I went to a local carpet store and bought padding that was branded "Spillguard - Barrier Technologies". The thickness I selected was 7/16". I believe that I used a spray adhesive both between the Dynamat and padding AND between the carpet and pad. Can't really tell for sure without pulling off my door sill (which I can easily do if you wish), and it was 3 years back when I did it. I can feel at the overlap under the seat that at least the carpet is adhered to the pad.

I cut the padding to fit all the way from the rocker to the transmission hump, but not over it. The look and the feel of it really comes out nice, but you need to make that pad trim against the tranny hump nice and tight or the gap will telegraph when you glue the carpet down.

I also made up patterns and had four custom black marine-grade carpet mats edge-bound, and that really helps keep the carpet nice when we are travelling. They look sharp enough that I usually just leave them in place even when I am showing the car.

Hello All --

I have in hand a new set of black loop pile carpets for my 1957 Chrysler
300C from Gary Goers, and am seeking advice regarding what padding to
use underneath. The disintegrating 36-year-old jute(?) padding - loose,
fibrous brown stuff nearly 1 inch thick (uncompressed) - is clearly no
good, so I will be using a modern, fairly dense foam type, as would be
used in a home or commercial application. I can get that padding in
thickness of ~5/16" and 1/2 inch.

Of course, I don't want the carpet to look too puffy or overstuffed, nor
do I want to reveal the numerous stamping profiles in the floorpan. The
"feel" of the carpet to the feet is also of little concern, since there
is no significant weight-bearing foot traffic on it -- the feet are
usually merely resting lightly on the carpet (except when a panicked
passenger attempts to "help" the driver stop the car from high speed by
stomping heavily with both feet on an imaginary brake pedal, like my
Mother often did when riding with Dad in "Big Red"!). The floorboards
are completely covered with a modern sound-deadening material with
aluminized face like DynaMat, so noise reduction is also of little concern.

I have been advised to glue the padding to the carpet with a spray-on
contact adhesive, but to NOT glue the padding to the floorboard. Does
that sound right?

Do you think I would be better off with the thick or the thin padding?
Any suggestions will be appreciated.
