Re: Heat/Sound Deadening Plan - Opinions?
2nd on the doors being a large noise source. Replace all the rubber and glass channels.
Otherwise looks like a good plan. |

Re: Heat/Sound Deadening Plan - Opinions?
Thanks all! Will definitely do the doors too.
Here's my progress so far. After removing the glued-on jute from the cowl area, and as much of the glue as I could get off, I painted the entire firewall with Eastwoods rust encapsulator. Then I added a layer of Siless closed cell foam to the cowl area, down to the firewall pad. The rectangular sheets are the perfect size for this job; they'll reach from the firewall up to the top of the cowl. Finally, I installed the cardboard-backed jute firewall pad. I got the pad from Repops. It fit size-wise well and most of the pre-made holes made sense, but it was half as thick as the original. I wasn't happy about that, so I glued on a layer of jute that is faced with aluminum foil front and back. I got the foil jute from Classic Industries. Together, the Repops pad and the foil jute matched the factory thickness. Also, the Repops pad came with plastic mounting plugs. I used new rubber ones. Here's a CRITICAL tip when installing the rubber mounting plugs: Debur the holes! If you don't, the ridge/burs on the holes will simply dig into the head of the plug and it won't go through, no matter how hard you try. A little grease might help too. Does anybody know how on Earth I'm supposed to install triangular column cover plate? I knocked out the hole in the pad for the column, but there's got to be more to it than that. |

You have got it down pat.
I helped my Nephew do (About) the same thing. It made a Huge difference in the road noise and heat difference.

Re: Heat/Sound Deadening Plan - Opinions?
I did two layers of killmat from the floor to just below the rear window along with some random patches under the dash I could reach while I had the cab stripped apart for rust repair.
I then put these on. https://www.jegs.com/i/Repops/629/CT307/10002/-1 https://www.jegs.com/i/Repops/629/CT306/10002/-1 https://www.jegs.com/i/Repops/629/CT522/10002/-1 and an underhood blanket. https://www.jegs.com/i/Repops/629/CT595/10002/-1 and topped it off with acc essex with mass backing carpet and the acc molded wall carpet (back of the cab). The install was quite a bit more time consuming that I thought it was going to be. A good pair of electricians wire cutters is the best thing to use to cut the holes in the carpet after poking through the bolt holes with an ice pick and making the x with a sharp knife. My scissors didnt cut it. Compared to the stripped interior (damn mice!) with the hole in the floor its a night and day difference sound and heat wise. Almost luxurious. |
