bed liner

[tazinva]

I have a lsvtec teg I pulled all the seats and carpet out of to clean I was thinking about putting bed liner as far up the fire wall on the in side of the car and on the floor pans and on the tunnel to keep the sound and heat down I know if will add wait but it won't be that much what do yall think

If its the stuff that you buy at pepboys or autozone i would'nt waste my money on it, i mean it will work a little on keeping heat out and very minimal noise reduction but not worth it your better off using undercoat. If it was up to me, which is what i done, i would dynomat it, not only would you be cutting out a lot of road noise and reducing heat you would be prepping for audio that is if you were planning on installing a system. You don't have to go with dynomat if your strapped for cash there are a lot of different brands out there, road kill, q-pads and cache which don't cost as much as dynomat. The down fall to using this stuff is that you will be adding weight.

Plus it's heaaaaavy

That it is, very heavy.

not entirely true. I put down 2 layers of dynomat in my 92 hatch (from floor to the ceiling and it only added about 26 pounds.

Bedliner is foam. And foam is mostly air. It will take about 4 cans of the brush-on, and 2 spray cans of the ... Well.. Spray. Put them in a box, pick up the box. How much does it weigh ?

Now follow me for a minute. Pop open the top and spread it on a surface. Say, a scale. Watch what happens when it's exposed. What you're seeing is "Closed Cell Foam". It will harden.

Enjoy your scuff and impact-resistant work-ready scale.

Ok, for whatever reason I thought it was heavy... especially seeing how it's commonly sold in 50 pound buckets, and reviews I've read seem to indicate an entire bucket of stuff or more for one bed covering. Haven't used it myself.

Well at Cartoys we use Dynomat a lot and I have dynomated a lot of cars and I know for a fact that a bulk pack weighs well over 25lbs and to do a civic floor board, trunk, doors and roof you will need 2 and a half bulk packs at a 150 bucks a box that's 375 bucks out of pocket and close to or over 100 lbs of added weight, but to me it's worth it as i don't care about weight issues just as long as i have a good looking car with some good sounds. Oh as far as the spray or brush on bed liner goes, that stuff is way way lighter than dynomat but does it compare to dynomat, NO. In order to get to the point of reducing heat and noise with the bed liner stuff it has to be pretty thick hence several coats, example you could spray 4 to 6 coats of that spray on stuff and it still wouldn't be as thick as one sheet of dynomat, waste of money in my opinion.

Supporting data ?

Here is the supporting data that i came up with so far, here are the specs on the dynamat xtreme and the herculiner roll on bed liner.

Here is another way we can compare the differences using your method Celerity.

Lets say we get two scales, now coat one with the roll on stuff and once its dry lets take them both to our nearest Cartoys or to anyone who carries Dynamat and ask them to give you a 1inch by 1 inch sample and place it on the other scale. Now that we have both scales coated were ready for test one, drop the scales one at a time on a hard floor and see which one makes the most noise, ( only the metal tray not the whole scale ). Test two, take a lighter and light it and place it under either one of the scales and place your thumb on the coated side of the scale and with a stop watch time yourself until you cant stand the heat, repeat the same steps with the other scale, i'm willing to bet the Dynamat wins.

He stated that he wanted to keep the heat down, but the heat on the firewall (Inside) isn't that bad. I'm not sure where he is even getting a concern with the heat.

As far as dropping two samples coating a scale, I sense you're trying to bait me.
