Well bare metal more or less. I am working on one footwell at a time, right now it is the front passenger foot well. I was thinking of recoating it with one of those bedliner-type products. But one that dries, not that remains soft and stinky like tar. One that ends up with a texture but dries hard while remaining flexible. At least, that is my plan until you give me a better idea.

Maybe one of these: http://www.mechanicalcaveman.com/best-diy-truck-bed-liner-spray-on-...

I used the bed liner on my last project, sticks like crazy, but the sound deadening results are not great, and bad fumes (eye watering) for a couple of days then OK.

The guys with money use POR 15 (?) with excellent results and so should you.

those should work, have to worry about off gasing but they should all dry and shouldn't smell after that.

have you though about a por 15 ?

They also make spray on sound proofing.

And they also make inexpensive silver padding for heat and sound proofing. Some people use sticky roof tar paper with aluminum on one side. I would be worried about off gassing with that but I think some don't smell.

Go to home depot and use your nose I would expect most to off gas.

I have a couple gallons of quietcar. Its like lizard skin.

I used por-15 with great results. I applied it liberally to the floors and only used half a quart. I let it cure for a week and then put n a layer of FatMat. I overlapped to try to keep moisure out. I removed the old firewall pad and used more of the same mentioned above. It really cut down on noise. Without the sound deadener, the car idled at 55 decibels. With the sound deadener, it is now 46 decibels.

Thanks. I knew about POR 15 but thought a) it's too ridgid and b) it wouldn't add any sound deadening. I guess that the bedliner would add some sound deadning but probably not enough. I was not aware of FatMax as an alternative to Dynamat. Dynamat is very pricy.

Over the weekend, I coated the floorboards of my 55 Desoto with Bill Hirsh Miracle Paint. Similar to POR-15. A few bucks cheaper, IIRC. Buy the Heavy Duty stuff. 

After a few hours, when the stuff had tacked up, I top coated with a rattle can of Rustoleum. Now it's going to dry for 48 hrs before I start reinstalling the interior.

With any of these Dynamat-style butyl/foil sound deadeners, can you apply carpet right over the material, i.e. onto the foil side, or do you need another form of padding under the carpet?

Remember I am a Noobie when I comes to car restoration, oops, I mean "improving" (over the current situation).

When we did the 944 with it, we used a thin closed cell foam over the top of it just for that little bit of extra reduction and to prevent vibrations. That said, you should have no issues putting carpet directly on on the foil. Its a metal foil on top that you use a roller to appy and flatten the checkerboard in the foil, Spray your adhesive and apply the carpet right over it.

Do your doors. It makes a HUGE difference in road noise, since you have no door speakers you don't need to baffle the outer skin, but closing all of the openings with sound deadener really quiets things down. I would use the thin foam over the top on the door.

Are you saying you noticed a huge improvement from covering the outer door skin or from covering the inner door skin? If you cover all the holes on the inner skin, what do you do if you need to pull the window or regulator out for some reason? These things tend to happen more often than I would like them to for various reasons.

Home made poor mans Lizard Skin.

I used Canadian Tire box liner as sound insulator base coating inside a pickup cab, but I mixed it with fiberglass microspheres (tiny air bubbles) that help as a heat insulator as well. Available at fiberglass supply shops cheap. It sticks, really sticks, watch out for the fumes while it is drying.

Well uncovered metal pretty much. I am chipping away at one footwell at once. At any rate, that is my arrangement until the point when you give me a superior thought.

I've ended up using the spray bomb version of the Duplicolor bed armor. Looks good. Dried well. Feels good. WINNER (in my mind).

spray bed liner works great. I would go with the non abrasion kind and then follow up with stick em sound proofer.

Rustproofing aside, sound deadening takes a multilevel approach.
There's no one-type cure all here.

Just look at how the factory tackled stuff like this on luxury models;
They used heavy tar plates on the floorboards, followed by 0.5" to 1" thick foam, backed to another .5" thick carpetting.

Heavy tar plates prevent floorboards from vibrating / resonating with low frequencies.
Foam dampens the midlevel frequency (road)noises and the thick carpetting 'absords' a lot of the interior sounds.

Today (Sunday, Oct. 15) turned out much drier and warmer that I had anticipated so instead of finishing off the trunk divider panel project, I went after the remaining three footwells. Which is a good thing because earlier in the week I was successful in placing an order with Stock Interiors for a cut and sewn Bright Blue carpet set for my 56 Dodge. So working on the footwells was timely.

I had previously finished the right front (passenger) footwell with various rust paints (but not POR15) and the Duplicolor spray on bed liner. Today I started in the right rear foot well. First step was to cut away as much existing carpet and very thin foam underlay. It wasn't bad only a couple of spots that needed attention. I went at it with my portable drill and cup brush and got the few spots that needed attention. Then I painted those spots with ZeroRust Black. When I was dry I applied the first coat of bedliner. (Only the initial condition shows in the photo below).

Much the same for the left rear passenger footwell. This one was probably even better than the right one. One of the body to frame stainless steel bolts was it very good shape after a little wire cup brushing.

The driver's foot well wasn't as good. There had been some water leakage at some point (the kick panels were both bad). Nevertheless, 20 minutes (or less) with the cup brush in the drill and a little selective scraping improved matters greatly (followed by vacuuming with my Home Depot Ridgid 42 L shop vac) (very quiet). Then I painted the area with Rustoleum/Tremclad Professional gloss grey rust paint (it is very fast drying).

Tomorrow I will add the second coat of bedliner to the rear footwells and start coating the driver's footwell. I will source some less than the price of Dynamat sound deading. That stuff is way expensive. (I did use some in my driver's door after I rehabbed it).

Thanks for all your comments by the way. Some of those products that you suggested are not available up here in the Great White North.

Photos of today's work (I should say, while there is some surface rust, there is also some evidence of red oxide primer - doubt that that was originally there):

From the looks of the pics and your description , you have just covered the rust issues. Rust needs to be 'killed' or the metal replaced. 'Rust Seal' is kinda like an acid that stops the oxidation process. It turn the rust black so you know it is working and can be painted over after drying. Should be able to buy it at a auto paint store. It's not to expensive, comes in a quart bottle. Try it you will be glad you did. Jerry

I did something like that on the right front passenger photo well. I used Rust Check brand "Rust Converter" spray. Turns the rust black and hard. I let it dry and then used Zero Rust paint and then the bed liner. That was so long ago (months) that I forgot to use the Rust Converter yesterday. Duh (LOL) Oops.

Oh well.

The under carriage is undercoated and this car will never see rain during my ownership (if I can help it) so the likelihood of further rusting in that drivers footwell is pretty low. That said, I will kick my butt for forgetting about the Rust Converter. I do have the two pieces of the driver's side footwell replacement metal should the next owner want to do that.

What is everyones thought about Corroseal https://4wdlife.com/best-rust-converters-for-truck-frame#Corroseal-W... ? For rusty parts. Its a Water based rust converter with high quality latex metal primer. Can be brushed on, sprayed, and is water based. I was thinking that it might be a good rust stop and then i could coat with any paint even Rustoleum after the corroseal has dried.

'56 your a thrifty one indeed sir. I priced some of them actuall for car sound deadening and insulation pads and man they are not cheap at all. I have been using rust converter by Rust Oleum on a few things. Not sure how it will actuall stand up, but have not had any aligator skin issues of in compatibilty. I have seen a few that have bought the flooring underlayment pad rolls at Home Depot, the silverish stuff, and have used it for padding. Not at all sure how it would work and what I worry about is being able to handle heat exchanged from exhaust being transferred to the floor pan. My Lil Red has carpet like padding only in the like sense.
