recently a Toyota Avanza owner bought all 3 types of my soundproofing products :)
here's his car :)
These are how SikaDamp630 should be installed! complete surface coverage on the flat metal skin. This skin has the potential to produce the most vibration(source of noise)
These are his SuperLon-ed doors! These supplement the Sika and acts as a sound barrier against further noise intrusion!
And not to forget the VibraTiles! We found it's very handy to stick is just about anywhere! Works great too!
his verdict?
he bought even more SikaDamp630 (another box) and lots more SuperLon for other cars!
HE is very satisfied with the sound-proofing of his car now, and he says he'll recommend it to anyone!
that's his testimony and i'm glad to do business with this gentleman :)
