possible Sound dampening alternative (not mat)

[ZombieFatMan]

So i have a K5 Blazer, it has Big side panels with lots of voids.
i have been looking at stuff to fill it in with .
Spry foam, Can spry foam, poly fill (teddy bear fluff), house insulation fiberglass, house insulation cellulose etc. on an on an on....

(just fyi i have dampening mat down and just ordered some Damplifier Pro for the roof, Spectrum for well everywhere )

i already did the tailgate with poly fill, and it works grate! but.... well that shit burns like wiled fire !!

today i was walking around the Big Box store and seen this

so tomorrow i will be doing one side panel with this stuff to see how it works.
its basically made from recycled paper. Yes paper , i know a lot of you will be thinking "Why would you do that !?" fluffy paper chunks , just burn your truck now an save time right lol
i just did a fire test an WOW!

i also got a few other things to try out ,

i have used great stuff lots of times but ran across this Black can for Big Gaps
going to do a expansion side by side test compared to the normal great stuff. black can is $1 more

i know i know Oooooo its evil .... im not lining my vehicle with the shit lol just for some odd spots ware i think water might get in.
going to give it a chance

Sounds like a good plan. Let me know how this works for you, because I have those same thin void side panels and they sound a mess

ya its a pain in the ass to have the voids , that poly fill works GRATE but it will go up in a flash . (wife was all in my ass about it lol)

so tomorrow i will put this stuff in . will have video tomorrow

Just one question though- How do you plan to apply that insulation to the body panels? Does it come in sheets or is it a bag full of fluff

Never mind im dumb lol

By hand , had full at a time .

It's dry fluffy stuff . I was thinking of reversing the shop vac too

[ZombieFatMan]

ok sides are full!
that shit is messy ! fine power covering everything in the garage .
but it works , hard to get in because its so crumbly . took for Eeeevvvvveeeeerrrrrr..........

i will do a sound test video later or tomorrow.

That looks like it sucked getting in there. Looks good and substantial though

I'd be worried about it getting moldy and smelling like mildew if any moisture gets in there.

i see its too late but do your best to seal all of that in. when the subs play they will flex those panels and little particles of all that fluff will get airborne. definitely make sure there isn't any fiberglass in that stuff too. when it gets airborne you'll be breathing it in. a friend of mine has scar tissue in his lungs because of broken up fiberglass particles he breathed in from his flexing headliner.

I just used the great stuff. 14 cans of it.... Every nook, the lil hose would fit.... ?!?!
