Sound deadening

[j0n]

I want to cover the entire inside of my iroc in sound deadening in an effort to eliminate rattles, however I'd like to refrain from spending the $1000+ paul spent on his camaro for dynamat. Any cheap alternatives that work well? I'm not trying to make my mad tyte system thump like whoa I just want to get rid of road noise. thanks

[NightRydaSS]

there is no cheap but effective way, at leat as far as im aware of and i sold sound equipment for over a yr.

bum.

[j0n]

fine ******* i googled it and the best product appears to be the RAAMmat BXT by RAAMaudio. It's not the best stuff on the market but it is by far the best value so I just ordered 3 rolls of 15"x50'

It is the little details that help. The lock rods/door hardware do rattle, and dynomat won't change that (unless they hit the mat, I guess). I put vacuum hose over them. When I put the 82 TA back together, I put a lot of what we called 'dum-dum' on the back of a lot of parts, especially dash parts. That car had zero rattles/squeaks when it was done. No dynomat (which would have cut down on road noise, no doubt). I'm sure the new GM t-top weatherstrip was a big help too. Anything you can do to tighten up all the areas that get a bit loose over the years and can't be tightened up very well anymore. A little shimming here & there, etc.

good stuff thanks...any idea on a guestimate for how much I should get?

[BonzoHansen]

Of the 3M stuff? 1 box is enough for a couple cars.

For stupid little stuff, don't overlook weatherstripping and such at Home Depot. I just used some to seal the heaterbox to the insdie firewall. I'll be using dum-dum for the HVAC case to the engine side firewall.

I know this post is old but I was searching for some info on this topic. My son told me he used some insulation from the home depot and it worked great for him. The price is so much cheaper also. Has anyone tried this in their car?
I'm thinking of giving it a shot.

OK I guess I'll be the first.

Why not try to eliminate the source of the noise by getting a set of subframe connectors and a strut tower brace?

3.4 - I used this stuff from lowes in the back of my tahoe to help with exhaust noise. I put two layers down from the rear seats back and it really helped alot. I have had it there for about a year and its still sticking like day one.

alot of perople uses the peel & seal from home depot then use a layer of reflectix for heat. Some love it cause its cheap and works pretty good and some love the exp name brand stuff. Its up to you.

[BonzoHansen]

No odors from that stuff?

[usp55]

None what so ever. We've had some nice hot days even this summer and with all the windows closed in the heat of the day there hasn't been any smell.

Rough estimate on how much it would cost to do 4th/3rd gen interior?

[HardcoreZ28]

Do you want to do the trunk area? Inside the doors? Up the sail panels at all?

Good to know!

[amargari]

I did mine in Lizard Skin ceramic coating then a layer of 1/4 inch Ensolite IUO Peal and Stick. Added very little weigh to the car and stopped all the heat from the floor.

trunk, rear wheel wells, doors, possibly seating floor

[WayFast84]

Would the ensolite iuo be the one for the heat? I need something bad!
