Saw in a forum, someone recommend GSI dampit! mat for door acoustic treatment and metal sheet anti-vibration.
Asked my friend, the shop he works has it, for RM secret. ha.
The mat is quite a big sheet, about 1m x 1.5 m. The material is not butyl, so it is more stable at wide temperature range (at least stable in Malaysia's weather) .I try it on my boot, you may not realize the existence, because I sprayed it to the boot color which is silver. Please click to enlarge it.
Next is the road test, I could find the humming noise from the rear tires is reduced, too bad I don't have an equipment to measure the dB reduced, I will purchase one soon.
