Which is better for soundproofing ?

[dripinrain]

When travel fast, i had to up the volume to compensate for outside noise.

Looked around & got 2 options -

Rubberised spray
Workshop will spray the undercarriage & wheel well. Also said to be good to prevent corrosion & stones hitting below.

Damping/soundproofing strips
Workshop will lay on floor until firewall.

As the cost for both is nearly same, i wonder which option i should go for. Hope to get expert advice from bros before i commit my $.

If you're into car audio as well then I'll recommend the no 2 option.

Dynamats are proven.. :-)

iam using 1 cm aircond isulator.
verry cheap if you do it your self.
costing less than rm100 for internal including inside door
but if you done it at acessories shop, it will cost you about rm800

for those aircon insulator(some call superlon - brand name) can go to upholstery shop to buy bulk or get those with adhesive from ninja_iqa(precut). my roof has 16mm of this stuff n really cuts the heat n raindrop sounds off, but what i noticed is, this superlon cuts out higher freq sounds better than mid n lower freq sounds so sounds like tyre n wind n muffler sound still gets thru.

Dear all,

Can try use Sika Damping (U.S product, toxic free) @ RM90 with installation.

superlon is for dampening, dynamat, sika, hustmat etc is for soundproof

good and reputable, i would say the following, dynamat, sika, and stp(this is the most extreme 1, from rmXX-rmXXX/piece also got, dun forget is juz cash n carry, not include labor yet)

Best reliable and cheap option is to spread thin layers of foam sheet in rear fenders and trunk. It really works, try it.

I would say go for both. Cut down both noise and you'll get rid of more noise~

Option 1 mainly for wind noise, option 2 is for road noise...It works differently.
