I got a roll of 5 meters from Lazada for RM178. Used a little more than 3 meters for all 4 doors so I'd say around RM120. The white cotton like thingy was RM17 per piece. Only used 2 pieces for both front doors. So all in around RM150.
I think what was priceless was the satisfaction of doing it myself for my car. I mean, if send to shop to do, you don't know how they'll handle it. If do yourself, you know you'll do everything carefully and slowly.
Started at 8.30am. Was done by 11.30am for 4 doors. But I took longer for the first door. Once I got the gyst of things, the other 3 doors were much faster and easier.
Road noise not so much. But it does help in reducing outside noise. Now when Mat Rempit zoom past, the sound is more muffled.

Even if you listen to music softly, (or if you're an audiophile like me), you'll definitely notice a difference in audio quality
Time to take it out and install bro. Now MCO ma.
