Okay, here comes the videos that I've promised!

Now, some of you might have experienced some 'tak tak' sound coming from the rear right passenger door whenever the car goes over road bumps, corners, or when the road is uneven. This may be caused by the rubber sealing on the car that turns dry after the car was parked under the sun or exposed to heat for too long. This method of identifying the source of the noise has been proven multiple times on a few members' car: Zapdos9, lhongwuh, and even my own car, and it's proven to work. However, this is not a permanent solution. The spray serves as a softener and conditioner for the rubber so that when it's rubbing against the door, the smooth surface of the rubber will reduce the friction with the door, therefore eliminating the noise altogether. It had to be applied regularly as the rubber tend to dry up pretty quickly. This is the only alternative solution to the mentioned problem, apart from having the whole rubber strip replaced. Please watch video 1 on how to identify the noise mentioned. Pay close attention to 0:12 and 0:27 to get a clear idea of what the noise sounds like.



Video 2 below on how to double confirm that the noise is indeed caused by the rubber, and the troubleshooting involved as well as proof that the noise is eliminated.



Done. As requested by Zapdos9

Yup. U'll get the sound more noticeably when u press the small triangular window. Probably because when u press on it the force is distributed throughout a smaller area.
