  • Sound deading material????

    If it is God's will I will soon be putting the new headliner in my 50 Champion. The bottom side of the roof was sandblasted and now it sounds like a drum when I close a door. What have others found to be satisfactory in this area. When I bought the car back this time, much of the old original material was laying on and discoloring the "new" headliner which I had put in 1988. I do not want this to happen again if I can help it.

    Also, I want to replace the similar looking material inside the doors since most of it came off while the doors were being restored-would the same material be used for this as for the headliner?

    Thanks to anyone who has had experience in this area who can help me with this project.

      I think the factory used a cardboard based liner of sorts. I would use a rubberized spray-on undercoating personally since it will be covered up anyway. I have never used it in exactly this application but have used it inside doors etc... and noticed a tremendous difference in road noise after spraying the floors of a noisy brand-X truck I had. You can buy cans of the stuff at your FLAPS. Steve

        ChopStu's suggestion is great, the Dynaliner sticky foam works well. However, try some Dynamat against the sheet metal, with Dynaliner over it. There are also other generic (cheaper) equivalents. Basically, the Dynamat is sticky (peel 'n stick) rubber with foil backing, about 1/16" thick which dampens vibrations. Then the foam over this provides acoustic AND thermal insulation. I used it for the headliner, floor, inside door panles, basically everywhere, and the difference was enormous.

          I used FatMat on the roof my Speedster and on the rust bucket I am now rebuilding. Stuck down good and does the noise job.

            Take care to investigate the long range characteristics of whatever you select. For example, a good modern undercoating material stays pliable and never really hardens...unlike the old stuff that would harden, crack, and eventually hold rust incubating moisture. The problem with newer gummy type undercoating is that due to the extreme temperatures setting in the sun...it could liquefy, run, and bleed through your headliner. Also, make sure any adhesive backed material is heat resistant so that it does not turn loose and drop down on the headliner. Good luck with it. Sorry I am better at telling you what to avoid than what to use.

                I used dynamat for part of the car and then went and bought a copy cat roll (dynamate look alike)on e-bay from Canada. about 1/3 the price. seems to work the same.

                  I'm gonna use that contractors grade (silver) double bubble with some heavy duty adhessive under my headliner, and also along floors and firewall. Possibly in the doors also. It is super light easy to work with works well and is cheap.

                    I would stay away from undercoating, I was in a pinch my local supplier of dynamat was out of stock and the upholsterer was coming to put my headliner in, so I did the old school thing and sprayed 3 quarts of 3M body Shutz on the underside of the roof, boy I am I ever dissappointed. Sounds like a tin can when I close the doors and it is hell in a hard rain, almost deafening.

                      I dont recall the price per roll, but any lumber yard or home improvement center has a .02 inch thick butyl rubber flashing tape (6 inches wide is common) with a white polyethylene film backing. This is very sticky and is used on homes for sealing around doors & windows. I havent used it for sound deadening, but if one layer isnt enough, you could add a second layer on top. Anyone ever try this stuff for sound deadening?

                        I got some stuff from Menards' about 1/16th thick, mobile home roofing repair type stuff. Very thin white aluminum on an asphalt type base with peel & stick paper on the back. 36 inches wide and 33 feet long, $79 on sale. The entire inside of my cabin (55 Pres Sedan) is lined with it. Mine is .06 thick, (nominally) three times as thick as the stuff above. I cut the tin can effect to about 40% of what it had been rain can still be heard, but it looks clean and sounds pretty good. Of course it's all covered up now, but it still is doing its job.

                          Thanks for the warning. Someone else seemed to think that it might bleed onto the headliner too.

                            Google "EZCool". Lots of hot rodders use the stuff. On Lubrocrod's
                            (I may have spelled that incorrectly) web site there are examples of tests done on the stuff. Reasonable price also.

                              I bought some foot square sound deadener panels (adhesive-backed) from the local auto body supply place. $33 for 6 pads, IIRC. They're called Q-Pads (Q for quiet I guess). I stuck 6 of them on the bare undersides of the Cruiser's roof and I gotta say I'm un-impressed with their noise quelling ability. I'm thinking about trying something else before I put the headliner up.
