Replacement tar mat

Recommended Posts

After 8 years of fits and starts restoring "Buttercup", a 7/70 build date 240Z (#7032) it has come down to the interior, which was completely stripped and the old tar mat removed.

While "Murdermat", "Fatmat", and the like are what are commonly used as upgrade/replacement--- I wanted the original deal--- as close to the factory fitment as possible.

After lots of net searching I finally found what I thought would be as near the original asphaltic mat as I was apt to find.

I bought the mat from AutoAtlanta FOR PORSCHE: WU890100, WU8 901 00 - READY TO SHIP - (WURTH FLOOR PAN TAR SOUND DEADENING INSULATING KIT) , a purveyor of restoration parts for Porsche autos:

I used a roll of rosin paper to trace the original floor mat outlines---- from the interior of another '70 240Z I had purchased as a parts car---- and cut out the patterns , traced it again and cut the new mat out with scissors.

Here's how that looks:

Next I proceeded to install the mat using a heat gun and a couple of hand tools to shape the mat to the sheet metal contours of the floor pans, transmission tunnel and rear hatch floor:post-8151-14150829737406_thumb.jpg

The mat has an adhesive and a release paper and when heated can be formed easily to the contours of the metal. It took several hours to create the patterns and do the install. I deviated from installing the mat on bare metal by painting all of the interior first, but the mat will be painted the body color as was done originally with a complete re-spray of the interior .

All in all I am satisfied with the product and offer this to assist to anyone wanting to do the same in the restoration of their Z.

Paint should follow in the next few days and I will post up a few photos when that has been completed.

Brilliant job. Looks neat and tiderly done with lots of attention to detail. Thanks for sharing. Murder mat is hard to find here, maybe this stuff is easier being a porche approved product.

Thanks Chas!

Should be easier for you to get.

It is made by Wurth--a German automotive parts and accessories supplier/manufacturer.

It has to be imported to get it to the states.

I dare say it will be less costly than Murder mat for you.

Carl,

I'll never be able to contribute as much as you have done to further the knowledge of these cars we love so much.

Without this website and the posts by members here, we would all be at a loss.

Many, many Thanks to You Sir!

Hi Dan and thank you!

Yes, carpet will be from "Chester & Herod"!

https://www.facebook.com/chesterandherod1924/timeline?ref=page_internal

Here's a quote from their website---

"Datsun 240z carpet

1970 in Hollywood

One of our most exciting moments came in 1970, when the owner created floor mats for the Datsun (then secret) 240z car. After making the carpet, he was is promptly asked to keep his mouth shut. Only 5 people in the country knew about the 240z."

I figure if these people were the selected shop to install carpet into the just released 240Z-- (which originally for the earliest cars, came with rubber mats only--RE: Arne and Mike B.)--then it should be exactly what I need. We had a significant discussion of jute and carpet on the forum several years ago. I am just now getting closer to it.

As for the jute--

I purchased it from "The Roadster Factory"---Carpet: Carpet Underfelt Kits And Underfelt Material, TR2, TR3, TR4, TR4a, TR250, TR6 :(page 38)

This stuff appears nearly identical to the original jute under-padding found in our Z'z, and is sold as replacement for British cars of the same vintage. (I.E. Triumph, Spitfire, MG and the like)

I purchased the roll goods rather than precut, as the shapes necessary for the Z cars differ.

When time comes for the install of the jute I will post up photos and patterns taken from the remnants of originals I have collected over the years.

All of this is meant as a resource, of sorts, for anyone wishing to fit their Z with original materials.

JIM,

This looks great. I am still uncertain on what to use to replace the original jute material. I would like your advice before buying any materials that may serve as:

Sound barrier

Heat reflection

moisture absorber which i believe is the purpose of the JUTE PADDING: http://www.stockinteriors.com/jute.asp?Itemid=4794

 

Your opinión on this will surely guide me making a final decisión on what to buy. Looking forward to your assesment!

 The problem with the original jute padding is that it does hold moisture for years, spreads it over a large area. No easy way to remove and dry it after it gets wet. I'd look for something else. You don't want a sponge under the carpets. If you do use a foam product, be sure it's closed cell.

My orange 240 has very little rust overall but due to a leaky valve at the heater core inlet and outlet it had seeped coolant for no telling how long and thanks to that jute my passenger floor board will need replacing someday.  For the time being I've got a "NO FAT CHICKS" sticker on the passenger door. LOL

@jalexquijano here's the thread on the gray spray paint for the rear finisher you were asking about.

Mark,

Okay! So instead of using the Stock Jute Padding in order to protect my new floors,  what would you recommend????? The shop is almost finishing replacing both floors and i need to place my order ASAP, if posible today.  AS advised previously i want a material that serves as sound barrier, heat dissipation and a Tar insulator as above.

Please revert shortly.

I haven't researched or chosen a product yet. I've still got a way to go before I put her back together. I do know that I'm not going to use the tar mat or jute. Many people have used Dynamat (sp).and have no complaints. I'll probably go with that.

Noooo, don't turn your your classic zed into a "TV resto" by putting in dynamat or something similar. Just put in the original tar paper like it was intended. Looks much better and very rewarding once you've slaved hours to put it in (burnt hands / sore back / am I selling it too you?).

It took me two days to put all mine in properly and I put in a great deal more than stock just to keep it as quiet as possible. Over the tunnel, new modern sound absorbing matting over the tar and the original restored vinyl over that. Floors have tar/double matting and carpet. Hatch area is tar/matting and carpet.

Should be quiet enough but nothing will stop the music the triples will make.

Planning on making some sort of heat deflector where the exhaust goes from the engine bay into the tunnel to help deflect the heat somewhat as it gets warmish on the passengers side (RHD remember). But doubt it will do much bit it may help.

Sheets of mass loaded vinyl backed with closed-cell foam has worked really well for me.  It's obviously not original, so if that's a concern, then it's maybe not a great option.  But it cuts road noise way down, won't hold water, and does a decent job blocking heat.  Also, it isn't attached to the floor pans, so it can all be removed in under a minute.

That is practically artwork there.   When I start my projects I picture them looking like that but when done they rarely do.  Definitely some real skill and patience involved.

I like this approach. Who was your source for the mass-loaded vinyl sheet?  How did the price per sq.ft. compare with the usual products like Dynamat?

Price is pretty good. MLV runs a bit more than $1/sq ft.  The adhesive-backed foam is considerably more expensive at $3/sq ft.  I buy from Super Soundproofing, but there are other places that sell the same stuff (eBay's a good source too).  Considering the size and weight of the materials, shipping can get expensive, so your best option will probably be the one that's closest.

Hi! Where did you got this material to substitute the Original Tar which i have the shop removing right now? I also read about this product which i intended to use and spray on after the shop finishes replacing both new floors panels and support rails and over a layer of POR 15:

http://www.lizardskin.com/sound-control-insulation.HTML (

Once spraying this product, i will cut and place the following JUTE material over it:

http://www.stockinteriors.com/jute.asp?Itemid=4794&MakeId=38&ModelId=313 (Automotive Jute Padding) as the original JUTE PADDING is quite expensive in my opinión: http://www.zeddsaver.com/products/datsun-240z-interior-insulation-jute-kit US$400.00

In conclusión, i want to be able to reduce all the road noise, heat and at the same time protect my Brand new floors. What do you think?

My panel guy told me where to buy it and it was a local shop here in New Zealand so sorry not much help I'm sorry.

I too had new floors must in. Etch primed then tar, then primed twice to stop the tar bleeding. Two top coats to finish it off. No problem with the rust coming back for some time I'd say.

More important attention under the car is the key here. It too was etched then two coats of a stone chip guard type paint, then top coats. As my car will live in a garage, hopefully helping in keeping the rust monster at bay for a while.

Pay special attention to ensuring that your door seals are good and also that the cowl drain hose that exits into the front guard void is in good shape. They can perish and the result is water soaking the firewall insulator and tracking down onto the floor pans.

Here's the drain hose in the center of the pic.  It connects inside the car to the underside of the cowl with a large hose clamp.  Very easy to get to inside, no need to remove the dash.  One on each side.
