Well I'm getting to the point for some insulation on the new project. A couple questions about the insulation. I'm probably going with Fat Mat. Never had an auto in a 69 but would the insulation go under the Horse Shoe shifter, or does the shifter have to be mounted directly to the tunnel?

I've seen some pics of the insulation on the doors, but wouldn't you want it on the skins of the doors? They had it where your hardware was mounted. The doors are new so I thought it would be a good time to install it with no hardware or glass in it.

Any other opinions of where to install or tricks welcome. I will probably be doing the roof too.

Thx's in advance...

First off there was a thread on here a while back comparing deadeners, independent study that was awsome will try to find it for you later. I went with second skin. Yes to doing the door skin but also put some on the inner door to alleviate any rattles. The door skin will become much stronger when applyed there. The roof should be done as well as the entire floor and inner fenders by the rear seat.

Hi,
I've still got my firewall and doorskins to do with Fatmat. Have done all over the floor and as much as I can do inside the inner quarters, whatever I can reach. I lovve the stuff. Get everything clean before you apply it, and it will never come loose. I put mine on a year ago, big difference so far. I definitely plan to do the inner skins and the inner door underneath the trim. So far it has rally taken away the "tinny" sound of the sheet metal. I think completing the doors and firewall will be huge in quiting things down, plan to do the roof also later. I am looking at putting some kind of foam mat over the top of the floor Fatmat and under the carpet to really quiet everything inside. I run Flowmaster 40's and before the Fatmat, the drone and resonance at idle at a stop light was truly annoying. Gone now.

I just got done doing what you're planning myself. And if I could do it again, it wouldn't use FatMat. I tried to use it on the roof, and it all fell off in a matter of weeks. Others have had good luck with it but not me. Good thing I didn't put the headliner in, cause I would've been majorly PO'd to say the least. After a lot of research I chose to go with Damplifier from SecondSkin.

Here's a thread I posted about my install :thumbsup:

I also used fat mat. so far so good I'm also running the flowmaster 40's and trying to kill the interior noise.

I've heard other people say that too, but when I applied Fatmat to a clean floor, if I tried to pull it up, it tore apart before it came loose. I live in SW Florida too, and it's been in for a year and just as tight (or tighter) than when I put it in. I honestly can't imagine it coming loose on a solid clean surface, but who knows. I will use more of it. It works well for me.

Coming loose on the roof was one of the things I was worried about living here in AZ. Not humid but interior of cars get plenty hot. It looks like most people have had pretty good luck as long as surface is clean. I too will be running series 40 Flowmasters and the wife would like a sound system in this car. I really wasn't going to run anything else on the floors. Did most of you guys add padding besides the FatMat on the floor?
Thanks for the quick rreplies..

I have it on my roof for almost a year now and its still
'clinging for its life" I plan to use it everywhere else on the car before I start the interior. Its on my doorskins too under the undercoating. My roof used to sound like a tin can. Now its a nice firm thud. I have all new sheetmetal as a start so maybe that helps the adhesion.

Hey Trax,
I looked at all your pics. You did one hell of alot of work. Nice job.

Dennis - I had no problem with 80mil under the shifter. There is a ground screw in the tunnel shifter area, if you put all the screws in place and cover them you can cut around the screw heads to reveal them. Here's a link showing some of the install.

When you read Jays thread, he's had good luck with Damplifier on the roof but I am a skeptic, if he had installed his roof 3 years ago and still has no problems it would really help sway me. I think he just did it a few months ago and I'm pulling for Jay as doing it twice sucks as it is. If it comes loose now it will fall onto his headliner...

For the roof I would recomend a spray-on in place of any stick on to avoid a problem later and wrecking a headliner. I think there are too many variables from moisture do to humidity or rain, how clean and greese free things are, heat as well as condition of metal the mat has to stick to. Gravity plays on a mat on a roof and even harmonics from the drivetrain or exhaust could play a factor in how long the mat stays before letting go.

Looks like that Spectrum by SS might be the way to go on the roof. Thanks for the links guys of your installs. Nice work. I only want to do this once but don't really want to spend $1,000 doing it.

Thanks Den for the info on the shifter!

Thanks RJ ! I appreciate the compliment. Cant wait to get it done so I can drive it..:)

PS You have one sweet ride !!!

I think maybe the batch of FatMat I got had something wrong with it. No matter where I put it, it wouldn't hold very strong. Roof, floors, wheel wells, etc. Even after going over it several times witha roller, butt end of a hammer, you name it. I had sprayed on Lizard Skin 2-3 weeks prior to putting on the FatMat. Maybe the Lizard Skin needed more time to cure before I put anything over it? The 1st time I did it in larger pieces, 2nd time I used several smaller pieces with gaps inbetween, and used foil tape to cover the seems.

Dennis,

Still no headliner on yet, I've been waiting till after the Holidays to get back at it. I've been checking it periodicly and the Damp/Foam is stuck like white on rice. I'm pretty confident it'll hold when the warmer weather hits. But of course, only time will tell......

Thanks for the compliment Gary. Get that car up and running!!! Post more pics when you can.

I used the spray on "Quiet Car" sound deadener. I did my doorskins with it. I was impressed with their video. Well... They still sounded like an echo chamber even with a couple coats of the Quiet car. I put the fatmat over the quiet car and it made all the difference in the world. Its dead and also stiffened up my doorskins a tad. I did test the fatmat adhesion to the quiet car. It stuck real nice. I did use a heat gun to heat the tar on the fatmat, maybe that helped. Then..weeks later, I coated everything with Eastwoods rubberized undercoating.

I do plan on comming up with some type of security plan before I get the headliner installed. I was thinking of some long strips of flat spring steel bands wedged in running across the roof pressing up on the fatmat, just incase it ever does want to drop. I dont know. I probably wont do anything. By the time I get done with the car and get to the headliner it shoud be on long enough to feel comfortable.

It's been 3 months since I put the Damp on the roof. It's stuck good, I think it'll be fine. I guess I could go over it one more time with a heat gun & roller for some added insurance. I've driven the car a couple times with all the sound deadening stuff installed. And even with no back seat, headliner, carpet, etc. I can tell it makes a huge difference. :thumbsup:

Dennis, I must strongly caution you against using FatMat. They have a long history of sketchy products and even worse custom service. Their deadener is identical to the Peel N Seal that you'll find at Home Depot for roofs. It's an asphalt based product. I haven't personally used any FatMat, but I have used another asphalt based deadener in my Impala. Every summer I find more pieces that have fallen off in my trunk and doors. Second Skin is really the best you can buy, but it is pricey. If SS is out of your budget, I would go with Raammat. People have had very good results with that.

There is always this controversy on sound deadeners in every post, which is good I guess. I have read that article that everyone recommends, but all I got out of it is that each product is pretty good, still up to the individual to choose, and everyone chooses differently, haha.
Once again, all I can say is that Fatmat worked for me. NONE of it has come loose in almost a year, and I just looked at it again yesterday, and I didn't go to any extremes in preparation of the floor, quarters, etc. And as for customer service, I ordered the Fatmat online, and on the third day, it was at my door. I don't know what more I could have asked from the product.
Anyway, good luck to all you guys just getting ready to start with the sound deadening. Just telling you my two cents.
Later,
RJ

Google, sound deadener showdown this guy did a real nice job on testing just about every kind on the market. He brought me to the conclusion to use second skin.

I used the generic dynamat all in floor, cowl, roof and doglegs, parcel shelf , floors, inside door skins . For roof I then applied contact adhesive , applied foil faced jute pad, foil side up for the roof. Everywhere else the this pad floats. I used the two sided bubble foil sheet as weather sheets. I have done this on both my Trifive and Camaro and roof is solid sounding. No issue with heat. Kills flowmasters and road noise.

Went on the SS website and thought I would shoot them an email asking what was needed for my application. I didn't expect a reply on a Sunday but got a very detailed breakdown of what he thought I should do (today Sunday). That's pretty good customer service. It was Ant that replied.

Ant's a great guy. He will also let you do local pick up to avoid shipping charges, but you have to pay sales tax. They're located about 35th Ave and Thomas.
