I am ready to install the door windows and quarter windows but would like to know what kind of insulation to use and the right glue to us to glue to inside of doors and quarters.I am also going to put insulation in the roof before I install the headliner. Ray

    Originally they just had a piece of tar paper glued to the inside of the outer door panel and the inside of the roof, they just used it for sound insulation and to give you the heavy 'THUNK' when you closed the door. Still the best thing to do for the doors and quarters as you've got the window mechanisms to look out for, but in the roof, you could use some fiberglass insulation batts. Just don't get carried away on the thickness or it will push down on the headliner and not look very good , trim them to the thickness between the roof panel and the tops of the headliner bows. Also get something on the entire floor of the car. You'd be suprised at the difference that will make. I don't know what they call the stuff, but Ace Hardware and probably most others carry rolls of insulation that looks like 'bubble pack' with an aluminized cover on it. It's a little pricey but it workls great. Good luck.

    Hi Duncan,

    Go to your local Auto Body & Paint supply store, and get some Q-Pads made by Fiberglass Evercoat, Part #116. These are as close to an OEM replacement as you will find. They measure 12" X 12" X 1/16" thick, and are pressure sensitive, self adhesive on one side, and come packaged 6 per box. They are not inexpensive, but they are made specifically for this application.

    Here is a link to the Fiberglass Evercoat web page for the Q-Pads:
    http://www.evercoat.com/productDetail.aspx?pID=50



    Note: The narrow Lt Blue piece to the left in the above picture is showing the removable liner of the self adhesive side.


    The Q-Pads are easily cut & trimmed to the desired size with some heavy scissors. Simply use multiple pads side by side, to cover the size area you need. They work for the doors as well as in the roof to replace the original heavy "tar paper" sound deadener that tends to be falling off the inside of these panels after 50+ years.

    Can't stress it enough to be sure to clean, strip, & de-rust the surfaces before installing as with any self adhesive product, any dirt or dust will keep them from sticking, and staying stuck over time.

    I have found that warming the pads, as well as the sheet metal panel you are applying them to really helps them to stick, and also helps them conform to curved surfaces without cracking. I have a heat lamp for drying paint that works well for this, or it also works well to just lay the Q-Pad adhesive side "up" out in the sun for a while before pealing the liner & installing. **Note that it is very important to be sure to rub them down completely with heavy hand pressure to fully activate the adhesive.

    These are not usually fast sellers at the body shop supply, so make sure that their stock is fresh. Can't stress this one enough! If in doubt, make them order you in a fresh batch as if they are old stock they will be prone to cracking, and breaking up while installing on curved metal panels, as well as the adhesive won't be up to par.

    Hope this is a help to you.

    There's also another company that makes a similar product for the same type of application called Dynamat: http://www.dynamat.com/products_automotive_introduction.html.

    They make different versions of their product for different applications. For instance a thinner headliner, thicker floorboard, more flexible door cover, etc... Haven't compared prices but variety IS the spice of life. ;-) Better to have too many options rather than not enough.

    Ever heard of Peel & Seal? They carry this stuff super cheap at Lowes and Homedepot. Many people have said it works amazing. I think you could do your whole car floor and all for under $65..

    I've used the Peel & Seal which is definitely much less expensive and great for the floors but the issue it has is with vertical surfaces. Peel & Seal actually uses an asphalt based adhesive (it's made for roofing) so it works great when laid down on floors and such.

    Unfortunately in extreme heat the asphalt adhesive turns gooey and starts peeling and eventually the weight of itself causes it to bubble away from the surface and eventually fall. I did the inside of a trunk a couple of years ago and all was great during the winter but once the Florida summer heat got to it I had a tarry mess and it smelled like I was paving highways in my trunk.

    I know lots of people use it but their environment may not be as severe as Florida is in the summer. I'm not saying don't use it, just approach it with caution and consider the application.

    Oh, here's a couple other brands that are a bit more cost effective than Dynamat:

    B-Quiet: http://www.b-quiet.com/

    Second Skin: http://www.secondskinaudio.com/

    Good luck!
