Okay I was pulling my interior to install my new dash & backpad. Down by my seat hinge I see some rust around the hinge mount. It was between the sound deadening factory stuff & the mount. It started around the mount & worked it's way across. I had one tiny hole through & some spots if it hadn't been seen would have gone through. Another gift from my car sitting outside at the wrench who screwed me a while back. He just keeps giving & giving (IMG:style_emoticons/default/headbang.gif) .

So I scraped all the sound deadening off on the rear drivers side pan. I treated it with some rust stuff I have. Tonight I scraped off most the front sound deadening. It was great with the exception of a little more around the pedal. I can tell it is just surface rust but it is coming out. I plan to use bedliner to redo the floor. Then I am going to paint it L80E to match my car.

Here are a few pics to check out of the area mostly scraped up. I haven't started on the passenger side but if it has the same issue I will get some before pics.

What have you used to replace the sound deadening (IMG:style_emoticons/default/confused24.gif)

you can use the dynomat stuff or similar product or you can by same tar you just took out from AA.
Or you can just leave it the way it is. I did and it doesn't seem to make much of a difference, especially with an engine right behind your head.

I've used and plan to use truck bed liner.....brushes or rolls on, real quick and easy......I bet if you start chipping that sound deadening material out you will find more rust (IMG:style_emoticons/default/sad.gif) check around your pedals, floor to rear fire wall seam. And seat mounts to floor

I used the reproduction tar mats that George offers on mine.
I had painted the car & floors prior so I left them (the pads) unpainted
I could paint them to match ..?
The nice thing about them was they are the same as OE material & already cut to the correct size & shape.

Yeah I have a little bit of surface rust by my pedal too. All the old sound deadening is coming out. I've got a buyer ready to go so I will dbl check with him. Maybe I will just get it prepped & he can put the stock matting in if he prefer's that. I like the bedliner as it will go below the pedal cluster too. As far as painting it after. I fI wasn't selling it I probably wouldn't bother. That black bedliner will look nice. Since 95% of the floor is covered anyway it isn't critical. Still it would definately scream not stock. As opposed to painted it most likely wouldn't even get noticed. I'll update with more pictures as I go through (IMG:style_emoticons/default/smile.gif)

Sound deadening ... (IMG:style_emoticons/default/rolleyes.gif)

There's tons of products available, including replacement tar mats that look almost identical to the stock tar.

I hate bed-liner inside a passenger car!
To me that screams redneck hack-job, sorry guys ...

Are you seeking a replacement that appears to be stock?
At the end of the day, its layers tar paper or roll roofing...
HD has both.

We use a similar product on the 356 cars....its just layered tar paper, glued together...and the final top piece gets put through a roller that has the exact same markings as the original.
That is really the only difference...

AA has taken the time and money to have this product made....so yes, he is the sole source provider of the stock reproduction floor mat products.

I would suggest that you strip and epoxy paint the floors, (por 15 type stuff) and then paint with normal paint afterwards.
Then put on whatever you want.

There are some spray on products out there , Lizard Skin is one, that have ceramic balls as part of the paint...so it has not only a texture, but a concentrated level of "dead air" by having the little ceramic hollow marbles in the mix....they are tiny and feel like sand.

Look around on some of the stereo and audio sites for reviews....seems like good stuff.
The idea with that stuff is spray it on both sides of the floors in a clear mix or black...then paint over it with the proper color.

If you are seeking maximum sound deadening, you need to do some research into what works, and how it works.
Sound is wavelengths...certain materials (aluminum and rubber) block certain frequencies (ala dynomat) and then when you add lizard skin as an additional layer, you block even more frequencies.
You need multiple materials to do the job properly...block the frequencies of the noise, and thicken up the panel to block the vibration that transfers noise as well.

The rear window is the weak spot for sound in our cars...
There was a guy a long time ago that did a double window setup on the back window...not sure if it helped.

Lizard Skin

Any bed-liner, including "Lizard Skin" is nearly impossible to keep clean and will always look dirty.

With a smooth surface, at least you have the option of cleaning it ...

Do you seriously get in and remove your floor mat tar boards and clean the floor?

I'm going to test some bedliner product tonight on a piece of old firewall. Once it dries I will paint it & see what I think.

If I like it? I am going to use the bedliner from the ledge down to the floor. I like bedliner for sealing up the floor. The tar mat may be a better sound deadening product. I may even use the tar mat on top of that afterword. In which case I may just order the 2 front pieces of the stock stuff. Just kind of in a hurry to finish the floor. Getting something shipped in a timely manner can be a problem.

By far the quickest way would be to just clean the floor and paint it (Properly i might add) and then lay down some dynamat or similar product and put the carpet over that. You can use some double sided tape to fix the dynamat either to the floor or even just to the backside of the carpet.

Quick and effective and it doesn't leave the new owner with the crappy redneck bedliner surface that he'll never be able to clean.

JC Whitney sells sound deadener. Some of their stuff is decent, and no different than what you will pay good money for at a "real" parts vendor.

(IMG:style_emoticons/default/evilgrin.gif) Andy I get it. Your not a fan of bedliner in a car. I do appreciate your input (IMG:style_emoticons/default/biggrin.gif) .
Until I test it & it meets my expectations it will never get into the car. I did mention once the bedliner is in place. It will be painted L80E same as my car. Therefore it should be able to clean up just fine (IMG:style_emoticons/default/confused24.gif) . I really don't know yet. Yeah I am leaning towards the bedliner. That can change real quick once I test it out. I won't know until I actually see it. Which probably isn't going to happen until tommorow night. Which also means I won't get to paint the test until the weekend.

The floor may just end up painted (yes properly). Then maybe some dynomat to help quite things up. I may snag some tar mat at Home depot to play with too. You guys have given me good advice & options. I will keep you all posted on what I do. Once my back recovers from all this scraping. I am using a Harbor freight multi tool with a scraper on it. IT does work great but man are my arms & back sore from just an hour at it last night. This getting old stuff sucks (IMG:style_emoticons/default/dry.gif)

Heating the tar with a torch as you go makes a WORLD of difference. (Don't know if you were doing that already, but just thought I'd mention it. Makes the scraper slide like butta.)

Ditto. HF milti tool cuts the old tar off in 30 minutes per side with no effort and right down to the metal. I kept a file handy and 'sharpened' the blade every 5 minutes to keep it cutting like new.

Lowes sells Air Conditioning rubber tape with a foil back. Super cheap compared to Dynomat. I applied 2 layers on the firewall and entire cabin floor, and it's quiter than the original soundproofing. Tape is about 3"wide on a toll like duct tape.
