Posted January 19, 201312 yr comment_412381 I have a 71 240Z. Most cars have something (cowboard,etc.) under the headliner. My headliner was glued directly to the metal. That is the way it was supposed to be glued isn't it? It took alot of heat. I want to put insulation (fatmat,etc.) under headliner. What adhesive do I use between insulation and headliner? Really good adhesive. Thanks alot Link to comment https://www.classiczcars.com/forums/topic/45453-headliner-question/ Share on other sites More sharing options...
January 19, 201312 yr comment_412382 Yes - the headliner was glued directly to the roof metal. There was a thin layer of foam rubber between the metal and vinyl headliner.I've had very good results with 3M SUPER TRIM ADHESIVE3M Super Trim Adhesive, 08090, 19 oz-Shop 3MThe adhesive that Nissan used originally is amazing stuff - 40 years in the Florida sun and the headliner is still firmly in place.FWIW,Carl B.

January 19, 201312 yr comment_412398 Two years ago I installed Dynamat virtually everywhere on my 73. However, since the original headliner is in perfect condition I didn't dare remove it. I'd really like to insulate the roof but wonder if any of you have done this. Did you re-install the original headliner or buy after market? Any problems encountered? Tips?Peter Link to comment https://www.classiczcars.com/forums/topic/45453-headliner-question/#findComment-412398 Share on other sites More sharing options...
January 19, 201312 yr comment_412399 I used a Dynamat when I refreshed my car - 2 years later the MSA replacement liner foam separated from the vinyl. Had to buy a new replacement and this time saturated the foam with adhesive. Time will tell.

January 22, 201312 yr comment_412597 I too have the MSA headliner and have not had issues with it over the 5 years since I installed it, but time will tell. The 3M adhesive products are a tad expensive but are well worth the money. Do not skimp here or else you'll have a drooping headliner.

January 22, 201312 yr comment_412652 How does the headliner look when install over the Dynamat product? Can it be seen? Link to comment https://www.classiczcars.com/forums/topic/45453-headliner-question/#findComment-412652 Share on other sites More sharing options...
January 22, 201312 yr comment_412660 No, assuming that you will be laying the Dynamat uniform and flat. Dynamat is heavy and the roof gets hot - I would be more concerned with all of that staying put. Perhaps another member can chime in....

Perhaps another member can chime in....Well there are other options as well, like spray-on lizard skin. They have two products 1) sound deadening and 2) thermal insulating. You spray on #1 and then #2. I suppose then you would adhere the headliner to that.

January 29, 201312 yr comment_413413 I used QuietCar - Now known as QuietCoat (QuietCoat - Leading Sprayable Viscoelastic Polymer for Noise and Vibration Damping). I was trying to just firm up everything, NOT attempting to make the Z acoustically perfect. The QuietCoat was sprayed into the Doors, Roof and Hatch, I gave it three coats except for the roof. Then I added several nice blobs of silicone on the edge of the Inner Door Supports. All of this reduced A LOT of the road noise and when you close the doors, they do not sound 'tinny' - but more like my Altima - a firm thump!The QuietCoat stuff is a waterbased, viscoelastic polymer that looks like a Charcoal Milkshake. You can spray it or apply it with a brush and roller. It is usually dry in 24 hours but I waited a week before reassembling the interior. The small two gallon size will probably do two Z's -unless you do the floorboards as well. The only reason I didn't use on my floorboards is that I used a aluminum heat wrap there instead. I am very satisfied so far - good stuff!! Link to comment https://www.classiczcars.com/forums/topic/45453-headliner-question/#findComment-413413 Share on other sites More sharing options...
