I've got some 10mm sealed cell foam with foil backing, left over from a project 10 years ago. I just had a play. Its a little thick for this application. Doesn't mold so well.

viewtopic.php?t=40934 Not sure if this is what you were thinking of, but it has worked well for me I can hose the interior out, i did not bother putting the carpet back in I did not find it too loud for free way driving and I was also planning in painting the underside in actual sound deadner from the auto body shop - which is the thick tar like stuff usually painted inside wheel arches.

This stuff is paint on so there is no where for water to be trapped between it and the floor.

[SierraDan]

Hmm, maybe I could dynmat the underside!

[christover1]

Tar paint on underside does work, used it on my Sierra, and trailer.
Never use it inside, it melts when it gets warm, makes a shocking mess.

Also would be a good idea in top of whatever sound proof thing u find, is to get some vinyl floor from an old jimny.

My jimny has it and its awesome. Sand and dirt its death eassy to vacuum and clean and if I get any spill it would just stay there as its plastic, unless it goes tru the edges. Not 100% watterproof but would be for most situations, plus u wont have a carpet soaking on watterever liquid got there

Check some wrecker jimnys

where is the sound deadening?

[Bugsta]

So I've ripped off as much of the cloth as I can. Scraped it with a knife. How do I get the last of it off?

I might just put the carpet back in as is and see whet the road noise is like.

are you talking about that carpet underlay?

you cant get it fully off it was glued on i scrapped mine off with a razor blade the best i could just be careful not to go through the carpet.

being 1/8" thick of basically rubber i think u will find it has reasonable sound deadening properties

[SierraDan]

That video was super gay haha.

But I am liking that sort of material.

there is no way the one coat they give that jeep is 3mm thick, maybe if you gave it 2 or 3 heavy coats.

[Bugsta]

Found this stuff in SortofCheap yesterday.

Any thoughts on water and sound properties of it?

Heard mixed reports on the dupli color stuff.

Just type it into google there are a few reports from the US.

Few people noted it went on thick but once it dried is was thin and fragile. Could possibly come down to their prep work.

Why not buy one can and just spray it on a scrap piece of steel and see how durable it is before applying it to your car?

[droverdave]

I have recently been making professional quality home hifi speaker boxes to plans provided to me by an acoustic engineer, and on the inside of the box i was told to paint this stuff onto it.

http://www.gripset.com/handyman/brochur ... ochure.pdf

what it basically is, is a water based rubber tar.....and it dries into sort of a very very hard rubber. hard to explain. Given its supposed to be used for roofing it must be quite durable?

For the speaker box application it was applied to the inside of the box, and the designer informed me that it was for sound deadening to keep resonance out of the box.

It might be good to use in this application for simliar reasons? and being a water proofing material as well it might suit as well?

[azzas15]

That looks interesting Dave.

This is from the information on that website.

"• Rust prevention, sound deadening and automotive patch work"

So could work well even on the inside

[atari4x4]

going by the usage notes it looks like it's not that hard wearing so you'd want to chuck the carpet or vinyl back in.

[azzas15]

Yeah it does mention it is not to be used In a traffic area but does mention it can be coated with a weatherproof membrane or acrylic paint which would offer it some protection

[Blakey]

you will be good with any bitumen based rubberized paint. the ones you can paint will not be all that great as they harden fully ones you can't paint will be more bitumen and stick to everything without a coating(thats why dynamat has the aluminum sheet on top. as its never dry's and is always sticky.

anything like that all works the same only difference between most is the thickness.

with the paint on stuff its going to be thin so its actually able to be painted on and you will need many coast to be anywhere near the same as the sheet style stuff like dynamat.

the dynamat i put in my jimny was about 5-8mm thick, thats a lot of coats of the paint on stuff to get near that.

if you want something cheaper then go a 5-10mm closed cell foam and glue it to your floor. it won't stop vibrations of the panels but it will block out a fair bit of noise.

dynamat dead ends by making the panel harder to vibrate preventing the panel from transferring the sound through it rather than actually blocking the sound. the foam blocks the sound by the sound getting trapped inside the closed cells and bouncing around ie breaking the sound up preventing it from going through.

plus the foam is a hell of alot cheaper, from clark rubber $40 for a couple of sq meters or $230 for a couple sq meters of dynamat.

that spray on stuff is the same about $50 for your whole car but a really thin coat.

no 1 coat will not be 3mm thick but if u do it yourself just do a couple coats or u can get it done "speedliner" will do it anywhere between 1mm- 150mm (but i think thats a typo and is meant to be 15mm)

i will be speedlining my jeep after i get it running again and ill let u guys know what it does for sound deadening

[pezz]

i did my old tj with speedliner whilst i was working a tjm newcastle(speedliner dealer)
it was a great product, but as a sound deadner i wouldnt rate it that well, nor as a heat blocker

but for a easy clean flooring it was great, especially when i had "pop up" bath plugs in the foot wells

[pezz]

will dig out some pic's of it of a cd soon..
the plugs were a bunnings item
press the plug down, it locks down, press it again, it pops up

yer i plan on using big marine screw bungs about 1-2" in dia,
but i want to cut the floor out and make a new floor thats 1" lower in the middle (like a shower floor) and put the drain plug there so when ever i fill it with mud (frequently) i can just hose it out.
i need to do the speed liner before i do the rear draws.

how thick was your speedliner and how do u rate the texture? is it rubbery or like sandpaper?

[pezz]

no real need to sink your floor, i just hose mine out(guiding the mud towards the plug,then wipe the rest toward the drain with a sponge

you can vary the texture with your nozzle when you spray it..
if you go to a speedliner dealer they will have sample plates to check out
you can coulor match and all with it
speed liner is a bit more flexable than rhino liner and doesnt crack as it stays slightly rubbery

cheers for the info mate id like to sunk my floor as even with 20mm hole in it its a bitch to get all the sand out all the time,
i was hoping u'd say it was rubbery in texture my father used a product called hippo liner i was more like spray on sand paper and would draw blood if u brushed against it
