Deadly Strips

The factory undercarriage sealant serve to protect the metal from rusting and also acted as sound insulator. As this rubber'ish seal aging; detoriated and harden, you may notice louder road/engine noise inside your car. Apart from applying another layer of sealant, the cheaper way is using bitumen strip. Bitumen strip are effective reducing noise, absorbing vibration and sound deadener. The downside of bitumen strips are, they are heavy and once they stick, it's going to be pain in the ass to remove them.

I bought 2 rolls of bitumen strips from a seller in LYN automotive garage sales forum. 1 roll is roughly about 10 meters long and 7.5cm width. Pasting at the spare tire area require less than 1 and half roll. The effect is quite noticeable especially the reduced interior vibration. I plan to stick this thing inside my door and under back seat sometime soon. For you peep who is very concious about putting additional weight into the car, this stuff probably will contribute an extra 3 - 4 kilos. But, if you drive the car as a daily commuter every now and then and wanting to have better driving experience, the additional weight from this bitumen strip is something you can compromise with.
