Bill Niles asked about insulation in doors..... Bill was right, there really is not insulation in the doors as built. The question you have to ask is why do you want to insulate the doors in the first place. Do you want a quieter ride? Do you want less heat loss? What are you after???? Heat loss is not usually a big problem....the large dead air space inside the door is a very effective thermal insulator. Most of the time insultion that is added to cars is for noise and vibration control.....dead air space is not much of a help here. Adding fiberglass batting would not be very effective at attenuating noise, although it will help some. What you really want to do is eliminate the source of the noise. Usual culprit is the vibration of the large unsupported sheet meCLnz ls (door skins, floorpans, roof panel) VW recognized and tried to help on the biggest culprit, the floorboards. They have ribs stamped into them to make them stiffer and they have the tar mats on them to increase the mass of the panel (mass damping). Ribbing the door skins is generally frowned upon by automotive stylist (one noted exception is our cousin the VW Thing). So the most common solution is to use mass damping. The Dyna-Mat and Road-kill and some others.....(I think JCWhitney has some that is cheaper) use this principal for noise control. Make the panel more massive (i.e. add weight) and it will not be excited at lower frequencies and thus won't make noise. As others have said this stuff is on the expensive side and it does add quite a bit of weight. It also very effective at reducing noise. I am planning to use it on my project Fasty. They also sell aluminum faced materials that are very good at reducing heat as well.....I will use it around the engine compartment. I don't think the spray-in foam will be very effective for noise. It is lightweight and probably won't attach itself to the steel panel very well. This attachment is critical if you want to reduce noise. It will also be difficult to make sure the windows and door latch mechanisms still work. It could also fill in the drain holes and promote rust as someone else already mentioned. Another option that will help some would be to spray a heavy layer of undercoating inside the door. (be still your healing heart Keith, if you are out there) If you do this PLEASE make sure the door drain holes are left unclogged. You do not want the door to fill up with water and promote rusting. Enough for now....I will let the list know how the insulating goes on the Fasty when I finally get around to it.
