I just wanna share my experience here.. It regarding sound proof using HARDWARE shop bitumen roll.. Not those bitumen which accessories use to sound proof.. Few months ago, I purchase alot of bitumen roll from hardware shop to do sound proof for my car.. Yes. I admit that I'm silly to done that cause I don't know the disadvantages.. After stick for 4 doors and my rear bonnet, it really sound proof! The noise from outside being minimize. Very happy.. And before I stick those bitumen on the door, I had clean the door surface very clean and no any oil.. After few months, da*n thing happen. I realize that alot black thing dripping out from the door and causes my side skirt look so dirty. I gonna to clean it and it so difficult to clean. So I remove the door panel and see.. All the bitumen drop off as the black thing get melt and the bitumen drop because the black thing which we stick already melt. Really so regret to done it. It so difficult to remove back all the bitumen.. I will post the picture tomorrow if you guy need to see.

This is the picture I done on my car last time. I will post the melt de by tomorrow... Newly stick, is look nice.. Once get melt, get mad.

oo sorry to hear that........and da*n smelly or not?

It not smelly because is odourless. But it look so messy after it melt. Picture will be capture tomorrow and post it by tomorrow as well...

yeah..last time i wanted to do it also to soundproof my car..but lazy ...need alot of time ..and have to buy the soundproof material also. lucky im lazy lol. can clean it or not?

it so difficult to clean.. And not 100% can clean those melt thing.. Sent to shop do is always better.. Like me, thinking can save money but at last use more money and effort. >_<

what is bitumen.

the one ppl apply to stop roof from leaking that one...got aluminium foil & black stuff...

yes.. I try dig see got the picture of bitumen or not.

yes, please do attach some pictures, so that other people will avoid.

I already uploaded some picture on first post.

haha.. i had this problem last mth.. damn it.. it messes up my boot area with lots of sticky stuff..

then how you settle ur boot area? Now I'm headache how to solve this problem.

I didnt know TS so silly go stick that for sound proffing purpose LMAO. This Roofing Sealent is meant for roof leakage repair and is really hard to remove it. It will melt under hot sun so that it will hold strong enough to the roof.

TS, just remove it using petrol or Thinner. And you will need alots of cloth. Before use thinner, u will need to scrap it.

we all learn from mistakes bro..at least hes sharing his experience so other forumers will be aware,not just senyap2 cover his mistakes..

I think not only me alone so silly. I believe still got alot out there which using this way.

Use petrol also thinner also no use.. Need to use heat gun to melt it then only can clean.. need use alot of cloth.

This exactly what I'm using. I bought it for Rm15 per roll...

that is soooooo cheap

it cheap, but it troublesome in the future.

Thats why people say not to use bitumen roll, but use proper sound proofing mats.

Thanx for sharing this info... i'm going to soundproof my car using this bitumen next week...

But after read this thread.. really not dare to try it anymore...

I did see those Car Accessories shop use this bitumen to sound proof their customer car... I know they use bitumen, coz they bought many rolls from my friend hardware shop. They charge RM400 for sound proof 4 doors.

My friend use this bitumen to sound prood his myvi too... If not wrong, already 1 year plus.. I gonna check whether that bad thing happen to his car or not..

i use superlon for 4 doors, more than 1 year already, now still ok

no wonder la say got problem
the way u stick also wrong already
i done mine for last 2 years ++ also
no problem

stick wrongly? Mind to tell me more about it?

you stick also stick huge sheet at once la don;t stick strips like that
if they come in roll, stick them side by side, leave no gaps.
after done, cover with one layer of superlon. baru soundproof

MAYBE Depends on the brand also..

My bitumen strips still ok after 2 years 5 months...the under bonnet also never melt..

btw stick wrongly how?

After taking off my panel to replace the transparent plastic sheet with a foam..

My 2.5 years old bitumen strip..


My 2.5 years superlon..


Recently installed EVA foam..

Another citical area, my 2.5 year old bitumen strip on bonnet...it's still hot even it's under the stock fiber based insulation cover. It didn't melt or got get harden.

@hypermount, your bitumen don't have any sign of melting.. But my 1, terrible.

@N's, i'm not free to snap the picture today.. Maybe I will try tomorrow because no time today.

actually does sound proofing really work?why is every1 soo keen to sound proof their car?not flaming or wat la,i just dont see y its an imp mod..

sound proof is really work for me. My cabin hardly can listen sound now.. Last time, my car just using this bitumen, it slightly better. The sound had been block and my ice getting better.. But recently, I just changed my tint film into Security Film which it anti smash, the sound proof getting better.. Only able to hear some motorbike sound pass by beside your car. Because the tint film is thick and block the sound from window.

add-on, forget a point.. When close the door, it sound better.

ohh..ok..just a few tiny strips to cover the holes in the door can make such a big improvement? where to buy superlon frm?maybe i shld try it out as well..and how u guys diy the firewall?theres a cazy amount of wires and not much space to work..

and yea i noticed when i drive with the door closed the cabin is quieter!

haha.. Sorry.. It should be, the sound of closing door is better..

I stick the bitumen doesn't just stick few tiny strips only. I stick it row by row... I not sure where can get superlon.. Maybe can see at garage sales.

haha ok i thought u were being sarcastic!btw u drive an iswara right bro? no offence, i had one b4..rattles like a tin can..can see y u decided to sound proof it..how many panels do i have to do for a simple diy job with satisfying results?

best sound proof material to me
dynamat~

Er.. yes I driving a Saga LMST.. Our car body quality, I believe all house have it, a milo tin or ovaltine tin. But, so far I dun face any rattles sound.. I only sound proof 4 doors, and rear boot to minimize my muffler bass and maximize my woofer bass. hehe.. Beside that, I also got stick sound proof stuff on my bonnet to reduce my engine sound. =)

dynamat expensive la bro..too costly for trial diy project

how bout the spongy material they selling at brothers? i side sticky the other side kilat like dynamat,in between got spongy material like superlon..not very cheap also but sounds promising as it has all the right elements..

make sure it not absorb water lor. or else, scare will rust your door.. Actually, you sent to shop do lor.. It more good, and more worth. =) But make sure do at some recommended shop lor.

And your car is black too. Heat absorbent. Thas is terrible.

It not terrible.. Is da*n 9 terrible.

black color, car also black color..cant see the diff la.

thats what u get by not doing it the right way and the budget way

Not doing the right way? Care to explain more?

ouch.. sakit hatinya.. habis kete TS..

damn kesian u man..i feel sakit hati see your car..those tar drippings can be removed? looks like ur power window motor aso gone..

yeah yeah... duno wat else will gone.. those dripping tar duno will drip and got stuck whr and make some other thg fail.. power window fail nvm.. the door lock also jam cos of the tar the jialat loooo..
TS btr clean properly oo..

Power window won't spoile as it didn't kena it. That why I gonna remove it asap. Tar dripping can't be clean properly. Unless you got heater gun, heat those tarc and then wipe with cloth...

Going try my best to clean it. =)

Added on May 12, 2008, 9:50 pmI just asked at some hardware shop.. Their told me no matter how you stick, it still will melt.. once it melt, then the bitumen is useless because it left the shinning part and no any glue to stick on.. I seen some said, stick this bitumen, you need to stick a layer on superlon above.. Once the bitumen melt, the bitumen will drop.So no point stick above the bitumen..I bought it for Rm15 per roll and I saw someone selling above Rm20 with same hardware shop material.. Although you guy know it cheap, but it not really wise to do so...

hey guys sorry if i revive this super old thread again but can you please give me the name of the bitumen tape that melted? seems like the picture uploaded here is gone or removed.
and btw i saw a guy posted somewhere in forum said that the vtech bitumen tape is fine to be use as soundproof. http://vitaltechnical.com/product/vt-420-v...-flashing-tape/
anyone experience or have thoughts to use this tape as soundproof? will it melt as well?

Please DO NOT USE bitumen of any kind to do sound insulation or soundproof your car. Use any type of foam sheet to do insulation. But do not use bitumen. Not big industrial ones nor the roll tape ones. Just don't. They add weight and are messy if exposed to non suggested operating environment and temperatures.

I drive a cheap car and am a cheap person, this is what I did to reduce noise from outside:

1. Insert aquarium tubes inside the door rubber seal. Spray some silicon grease inside the tube before inserting to lubricate the insertion.

2. Spray rubberised undercoating inside the spare tyre well and inside each wheel well. I use Bondo spray (3M product) bought at Ace Hardware.

3. Bought cheap self-adhesive sound insulation foam from Ali, tampal behind plastic fenders.

So far so good!

Make ur car sound proof, so to avoid hearing other car honing u like accident gonna happen?

Belilah 3m thinsulate. Let me know if you interested
