whats a good Dynamat alternative thats safe for the longhaul?

[RedShadow30]

So before i continue i know im about to get picked apart so ill get it out of the way now, I bought an 86 toyota corolla.

Everyone done laughing at me? Okay heres my siuation.

I was holding off on doing the carpet work on my charger till I could afford to do it right the first time. Well I ended up getting my second dream car as a DD, an 86 corolla with also no carpet. After seeing how much dynamat costs. what is something i can use? Ive seen knockoffs and home depot tricks, but i want something i can use that i know will stand up to the florida heat and the noise. Both my Charger and Corolla have 100% no floorpan rust and both have spray in liner, so what i put down i never want to come back up. Can anyone tell me of something cheap thats long lasting or is dynamat worth the extra cost?

Your still laughing at my corolla arint you?

Here is what I used on my 67 and 73. When I had my 67 floor pans replaced, I found this. Excellent heat reduction and very good sound deadening. And the price is MUCH less than Dynamat for essentially the same material.

Depot and Lowes both carry it.

I just finished covering my interior floor of my cuda with Hushmat. Much cheaper than Dynamat and virtually the same product. Summit Racing sells Hushmat but under their own private label, but it will arrive in a Hushmat box. I paid around US$3.70 ft2 locally when on sale.

I don't know about sound proofing, but I'd like to see a pic of the car, I like some of the little 4 cylinders. I have a 91 Dodge colt all wheel drive turbo project, for a time when I have more money. Now they can laugh at me too.

STP Black Gold is great.

I used Dynomat in my 64......Then found an as good or better product, with better features.
The dynomat came so wrinkled that it was hard to apply. Never again.
I'll get the name of the other brand and post it here later.

I had heard that about Dynamat too. I saw the STP stuff I got, going into another car before I purchased it. It is totally flat, rolls on easily and with the little nylon roller that came with it, it flexed really easily into the bends and contours.

NVX...........40 Square feet for $120.
Easy to apply and it has ship lap ends so you do not have to but pieces together and then have to use seam tape, + the protective paper is about an 1/8 " over lap so it is easy to get the paper off.

This site has a lot of interesting information.

Thank you all, I had no clue there was much more than dynamat or some of the smaller brands. With my corolla not to concerned about the heat side, just with a 2in exhaust and resonator i want to get the sound and vibration down. With the charger i am concerned about heat because i have seen carpet catch fire and why i keep a fire extinguisher within reach of the drivers side. Maybe when i get home ill get a pic of the corolla. I could probably park it in the truck of the charger.

This is what I bought but not installed yet. Glad to hear your recommendation
I am going to use "Boom Mat" along with it.........................................MO

ODZKing, How much of that product did you use to cover your car, how many sq ft? I'm very intrigued by your post and I'm thinking about doing that too my 70 RR in the next couple of weeks. Thanks for the info!

 

[ODZKing]

For the 67 about 2.5 rolls. And the 73 which, believe it or not actually has more area to cover 3. At $13-15 per roll it was significantly less expensive than Dynamat. There are 2 types, one with and one with out the self adhesive backing. I chose the adhesive as it stayed nicely when I put it. Sealing the seams with the tape was just a precaution to keep the edges from rolling up as they easily do with this stuff. I suppose any tape would do but the silver also worked nicely. All toll I had maybe $50 into each car as I had a bit left over from the 67 including the roll of tape to use on the 73.
It molds nicely and all in all I was very pleased with it's performance.
There are pics of the 73 in this restoration link about half way down.

I went ahead and used your method ODZKing. It came out pretty damn good. After a few weeks of fiddling around with some other wiring and so forth, I finally got the interior back in and took the car for a ride. It's not magically transformed into a quiet Japanese car or anything, but it's noticeably better. In particular the Flowmaster drone is much less now with the insulation. And I ran it from the top of the gas pedal all the way to the back where the floor turns up into the trunk. I especially put extra layers over the driveshaft tunnel. Very happy with the results. I used 3.5 rolls to do the entire job. Here's a pic before I put the interior back in.



Also I installed 3 point seat belts in the back seat for the kids. They came out awesome as well. You can see the 3 spools on the package tray. Now the kids will be super safe when riding this summer!

 

[ODZKing]

Outstanding, I glad you're pleased with the results.
Easy to use and form wasn't? :eusa_dance:

 

[petieg383]

TOTALLY. It cut real easy with a razor and was real easy to work with. I used a rubber mallet to rub and push it into place just to put a little force on it. Using the adhesive backed type was the right move too.

I know removing the interior isn't the easiest job, but it's also not the hardest. This wasn't a big deal. I completed it in a few nights and I think it's made a difference. And I spent about $80 total.

I'm going to be putting a few hundred miles on it in a few weekends for a road trip. I'll know more then.

Thanks again for the inventive idea.
