Tayyab Bhai there is a marked difference in level of noise from before and after dynamatting ... I can say, about 70% noise is gone.
Whatever noise is left comes from the front wheel arches and the firewall .. they can be done when some professional dismantles the dashboard
I already told you about the butyl rubber thing ... the shopkeeper just sandwiched jumbolan between the plastic door trim and the inner sheet metal ... he did not do the butyle rubber thing ...
Today I had a lengthy phone conversation with our friend Dr. Tanveer in Karachi ...
He got a thick coat of rust proofing under the car .. I asked him to check the sound after removing some portion of carpet ....
the effect of dynamat is very profound ... tapping an un-Dynamatted portion of the car with knuckle of your finger produces normal sound ...
with the dynamat on, if you tap it with knuckle .. then you hear almost the same kind of sound if you tap a concrete wall with it ... no more metal sound ...
