So im getting rattles in my doors, headliner, rear speaker area, and pretty much everywhere else. I was looking at dynamat but its pretty expensive. Has anyone used something other ( cheaper ) than dynamat that has worked pretty well?
dynamat alternitive??

why not take the door panels off and see what's come loose....greasing the moving parts can help stop rattles and the rattle in the rear speaker area could be from the speakers being loose or something in the trunk, like the spare tire, that's making noise....the headliner is one area that shouldn't be making any nose tho....I plan on dropping my headliner to place a piece of sound deadening material since I removed the vinyl roof the tin roof sounds real tinny
I bought some frost king ducting insulation from Home Depot. Was able to do my whole roof for under $15. You need a can of 3M glue though. It is tacky but not sticky enough without glue. Probably not as good as dynamat but way cheeper.

I have. Eveythings bolted solid, though i didnt grease anything. Im thinking it might just be the door panel vibrating on the metal of the door.
Also, ive never worked with this stuff before so if anyone has any installation tips, espically in the door areas, it would be appreciated. Thanks!! 😀
do you still have the sound deadening material GM put on the doors?...that usually stops any rattling of linkages on the door and take a look at your door latch since that could be the source if the rattles...
I've used some cheap stuff I bought off Ebay that I believe it just a form of roofing seal. It works great on the floors and doors but I've had problems getting it to stay put on the roof of the car.
I use a heat gun and a roller and it adheres fine and doesn't move it when its colder out. But come summer when it gets hot in the barn, the stuff starts sagging.
So for the roof I'm probably going to buy the good stuff at least.

The facotry sound deadning stuff is pretty tattered in some spots, it might as well not even be there. Ill check the handle. Even if it does stop the noise im prolly gonna do it anyways, as well as the floors, roof, mabye even firewall for insulation and excess road noise.
FE3X, i saw some stuff called pull n peel, sounds like the stuff that ur talking about, but i heard it has a pretty strong tar smell to it, which i defintly dont want. Did the smell fade after a while?
For installing it in the doors, do i want to just bond it to the metal parts, and cut holes where there are openings to the window regulator/track, or do i want to cover the entire door? Any thing else i need to know or is it pretty self explainatory?

The stuff I have doesn't have a huge tar smell to it.
However the Peel n Seel stuff does have a tar/asphalt smell. I didn't think it was that bad though. I left a roll of it open in my car one day during the summer while I was at work just to see if when I came out at lunch it would smell. Wasn't all that strong.
Now in my '87 I have two to three layers of a sprayable sound deadening on top of the sound deadening mat so there's no smell going to make through that.
Which brings up something else. I've used the Cascade Audio sprayable coatings which work really well. The spray on purple and dry black. Makes it super easy to see where you've sprayed and were you haven't.
It also helps if you can sandwich the metal with the sound deadening on both sides like the floors. I have one coat of an insulating/sound dampener spray that I bought from Second Skin Audio. Then two to three coats of the Cascade Audio sprayable sound deadening on the underside of the car.
Inside the car I have an 80mil layer of sound deadening mat on the entire floor and up the rear trunk divider. Then a layer of the same insulating/sound deadener as under the car and another coat of the regular sprayable sound deadeners. On top of that I have two layers of 1/8" Volara foam with a stock rubber sound deadening mat on top of that. Then the carpet.
You can smack the car with a hammer it just a get a dull thud. I also tested the sound deadening mat in my trunk where I put a layer of it on one 1/4 panel and left the other one bare. Then I cranked up the music and it was amazing how well the stuff works. You put your hand on the side without the sound deadener and you could clearly feel the metal moving. On the side with the sound deadener you could hardly feel the vibration on the outside of the 1/4.

Do you remember what the roof stuff you bought was called? Im just doing the doors now ( when it warms up ), the floor and other stuff will be later when i go to change the carpet. Thats weird that the stuff on your roof sags when it gets hot, you would think that if it is made for roofing it could handle the heat of a car.
